HD Royalty-Free Image Sites: 10 CC0 Licensed Photo Galleries with 3 Million+ High-Resolution Photos
Let me share a real story. A friend of mine who runs a media account used an image from a Baidu search in a blog post. Half a year later, he received a legal letter from Visual China — demanding 2,000 RMB in compensation. He was wronged: "It was on Baidu, how was I supposed to know it was copyrighted?" But the law doesn't care whether you knew or not — using it means using it.
Since then, I have only used CC0-licensed image assets. CC0 — the creator waives all rights. You can use, modify, and distribute them freely, including for commercial purposes, with no attribution required and no restrictions whatsoever. This is truly safe, free imagery.
After using these sites for years, I have compiled the 10 most frequently used, highest-quality CC0 galleries. But this time, I want to write it differently — no formulaic "key strengths 1, 2, 3" — just my genuine experience using these sites.
Unsplash: The Quality Ceiling, But Not a Cure-All
Unsplash was the first one I started using, around 2018. Three million photos, and the quality is truly ceiling-level — photographers worldwide actively upload work, every shot taken to professional standards.
After using it for a while, you will notice Unsplash leans artistic and "Instagram-style." Landscapes, coffee, notebooks, window light — these photos are top-tier. But if you are looking for "factory production lines" or "Chinese street scenes" with an Eastern aesthetic, it falls short.
English search results are far better than Chinese ones. Searching "business meeting" yields much better results than "商务会议" — after all, these sites are Western, and English content is richer.
No registration required for downloads; click and you get the original image — very straightforward. Access speed from China is average; occasionally you need a few seconds to load.
Best for: blog header images, PPT slides, website backgrounds — almost anywhere you need a "good-looking image."
Pexels: I Can't Leave It Because of Chinese Search
If I could only pick one photo gallery, I would choose Pexels.
Not because its image quality is the highest (honestly, Unsplash is better), but because Chinese search actually works. Searching "美食" (food), "办公室" (office), or "自然风光" (nature) yields results nearly as good as English searches — incredibly friendly for Chinese users.
1.5 million images — fewer than Unsplash — but it bundles images and videos together. When making a PPT, I occasionally need to embed a few seconds of video background; Pexels has them directly, no need to switch sites.
The interface is extremely clean — no ads, no tricks, no registration required. Access speed from China is better than Unsplash.
Especially suitable: everyday image needs for Chinese users, for both photos and videos.
Pixabay: The One I Remember When I Need Illustrations and Vector Graphics
Pixabay's image quality is slightly lower than Unsplash, but it has something no other site offers — a massive collection of free illustrations and vector graphics.
Out of 2.8 million assets: 1.8 million photos, 300,000 illustrations, 400,000 vector graphics, 80,000 videos, and 100,000 music tracks. Looking for icons, illustrations, or vector graphics? Pixabay is the place. When making PPTs, I often need small icons — search for SVG format on Pixabay, change the color, and use directly.
Full Chinese interface, good Chinese search, fast access from China. Completely free with no paywalls.
Picjumbo: Unique Style, Modest Volume
Picjumbo is a niche, boutique photo gallery — run by a single photographer with extremely high image quality.
It is niche because the volume is only around 100,000 images. But the advantage is a distinctive style — leaning fashion, lifestyle, and food. And because the content is exclusive, you won't find the same images on other galleries, reducing the chance of "photo collisions."
After registration, you can download curated photo packs — for example, searching "food" might yield a "Food Photography Asset Pack" with dozens of images to download at once, saving time.
For e-commerce, food blogs, and lifestyle content — Picjumbo images add a sense of "premium quality."
Gratisography: Come Here for Creative Images
Gratisography's founder, Ryan McGuire, is an eccentric — he specializes in taking creative photos that "normal people wouldn't take this way."
Only about 10,000 images, but each one is his exclusive work. Surreal, quirky, mind-boggly creative compositions — you absolutely won't find similar content elsewhere.
I once made a social media marketing PPT and needed a cover image that "makes people click." I eventually found a giant hand reaching out of a computer screen on Gratisography — the effect was outstanding.
Updated every Thursday, not many images, but every single one is a premium piece. Designers and marketers looking for creative visuals should definitely follow it.
StockSnap: Niche but Excellent
StockSnap is something I only discovered in recent years — a bit like a "curated edition" of Unsplash.
300,000 images. The volume is not large, but every image is manually reviewed; low-quality content is rejected. Views and downloads are public — you can see which images are most popular.
The "Trend Tracking" feature is interesting, showing the most popular image styles right now. I find that after browsing extensively, my sense of PPT color matching and layout improves almost subconsciously.
The search suggestion feature is also useful — entering a keyword auto-suggests more precise terms, saving a lot of trial and error.
Burst: E-Commerce Image Heaven
Burst is an official product of the Shopify e-commerce platform — an image gallery designed specifically for e-commerce professionals.
50,000 images, not a large number, but all commercial scenarios: office, retail, products, fashion, technology, food, business... If you run an online store, design product detail pages, or do marketing promotions, Burst is the perfect fit.
The images are all shot by professional commercial photographers, with composition and lighting perfectly suited to product displays. I once helped a friend find "coffee beans" and "handmade leather goods" for a product detail page — the results from Burst were much better than expected.
Industry-based categorization is also convenient — fashion, technology, food, business — just click and go.
Life of Pix: European Photographers Have a Different Texture
Life of Pix is run by a Canadian production company, featuring exclusively European photographers.
European style is distinctly different from North American — leaning artistic, cultural, and architectural, with a quiet, light-and-shadow-focused texture. When making an annual corporate report, I used its architectural and city photos to create a "small but beautiful" visual effect.
Only 20,000 images, but the quality is consistent. Editors select the best images weekly, so you can go straight to "Weekly Best" instead of scrolling page by page.
It also has a sister site called Life of Vids, offering free video assets — video creators should check it out too.
Kaboompics: Searching by Color — A Feature I've Wanted for Years
Kaboompics is run by female photographer Carol McCarthy, with a fresh, soft style — lots of lifestyle, home, and food scenes.
But its most stunning feature is color-based search. Anyone who does design knows that sometimes you don't need a specific theme — you need a specific color tone. Making a blue-themed PPT? You want all your images in the blue family. Kaboompics lets you search directly.
50,000 images, CC0 licensed, completely free. It also offers image compression and color adjustment tools — a thoughtful bonus service.
Best for: feminine products, home lifestyle content, food blogs, and series designs requiring a unified color palette.
Negative Space: Minimalist Style, Lots of White Space
Images on Negative Space share a common trait: generous white space and minimalist composition.
PPT makers should understand the value of white space — you need to overlay text on images. If the image itself is cluttered, text is hard to place. Images with white space make adding titles effortless.
Browse by color, category, and space. High resolution, updated weekly. 20,000 curated images, CC0 licensed.
Best for: PPT slides, website banners, and scenarios requiring text overlays.
Recommendations for Different Scenarios
Blog images / Everyday use
Start with Pexels or Pixabay — Chinese search is convenient, access from China is fast, and the images are practical.
PPT presentations
Unsplash and Negative Space are the best combo. The former provides high-quality visual content; the latter provides white-space images perfect for text.
E-commerce / Commercial scenarios
Burst is the top choice — it was literally tailor-made for this scenario. Pixabay as backup.
Creative design / Avoiding photo collisions
Gratisography and Picjumbo have the best uniqueness. Especially Gratisography — those "mind-bending" images truly cannot be found elsewhere.
Illustrations / Vector / Icons
Pixabay is almost the only option — other large CC0 galleries don't offer vector formats.
Video assets
Both Pexels and Pixabay have video sections, CC0 licensed for direct commercial use.
Practical Image Search Tips
English search results are far better than Chinese — the content on these galleries is all in English. If your English isn't great, search in Chinese then quickly switch to English keywords; the difference is obvious.
Combined keywords beat single words. Searching "business meeting office" works much better than just "business."
Orientation filtering matters: landscape for blog headers, portrait for mobile screens and social media, square for product images and icons.
When you find an image you like, always click "Similar photos." This feature is the most efficient — it saves far more time than searching a new keyword.
Pitfalls I've Stepped Into
Don't use Baidu Images. 99% are copyrighted — this is a major infringement hotspot.
Don't use "free" assets from sites like 588ku or 868ku. "Free" is a trap; commercial use requires payment. Their license terms are extremely vague, and you'll never be able to explain yourself clearly.
Don't use images from Huaban. Huaban is a user-curated platform; copyright belongs to the original creators — you have no authorization.
Visual China, Tuchong Creative — legitimate licensing but expensive. Their "free" sections are actually watermarked preview images.
Another easily overlooked pitfall: when using CC0 images with identifiable faces, there may be portrait rights issues. While copyright is waived, portrait rights are an independent legal concept. CC0 galleries generally require model release forms, but not every image has one. If you must use images of people, prioritize well-known galleries (Unsplash, Pexels), which are more rigorous in this regard.
A Few Image Usage Habits
HD images must be compressed — using originals directly in web pages or PPTs makes loading painfully slow. TinyPNG or Zhitu (智图) both work; 100-300KB is clear enough for web use.
Maintain a consistent style across images in the same document. Keep color temperature (warm/cold) and composition (close-up/wide) consistent, otherwise it looks like a random collage from different sources.
Place text in the white space of images, or add a semi-transparent overlay to improve readability. Never put text on a busy, cluttered part of an image — it becomes completely unreadable.
The beauty of CC0 licensing is that you can modify freely. Color adjustment, cropping, filters, compositing — all fair game. Always process images; never use them as-is. Two creators using the same unprocessed image? Awkward.
I've also developed the habit of going directly to these galleries for images instead of Baidu. Save a screenshot of the license, and build good copyright awareness — it will benefit you for a lifetime of content creation.
