Need to compress, resize, convert, or edit an image right now? These are the 10 best free online image tools in 2025 — all work in your browser, no download needed.

How we evaluated these tools

We ranked each tool on available features, privacy (whether files are uploaded to servers), ease of use, and actual free limits. Every tool on this list has a usable free tier.

1. Canva

Best for: Creating designed images from scratch.
Canva is the most popular browser-based design tool in the world. It's technically an image creation tool rather than a conversion or compression tool, but its free tier is extraordinarily generous — thousands of templates, photo editing, background removal (limited), and export to any format. If you're making social media graphics, Canva is in a class of its own.

2. Adobe Express

Best for: Adobe-quality editing without Photoshop.
Adobe Express (formerly Adobe Spark) gives you photo editing, background removal, resizing, and text overlays for free. The free tier has limitations but the quality is high. Files upload to Adobe's servers.

3. Photopea

Best for: Photoshop-level editing in a browser.
Photopea is remarkable — it's essentially a free browser-based Photoshop clone that opens PSD, XCF, AI, and PDF files alongside standard image formats. It's ad-supported on the free tier but fully functional. If you know Photoshop, you'll feel at home immediately.

4. Pixlr

Best for: Quick photo corrections and filters.
Pixlr offers two editors — Pixlr X (simple, beginner-friendly) and Pixlr E (advanced, closer to Photoshop). Both run in the browser. Free tier includes most tools. Files upload to their servers.

5. TinyPNG

Best for: The best PNG and JPEG compression available.
TinyPNG uses smart lossy compression specifically designed for PNG and JPEG files. It consistently outperforms other compression tools in file size reduction. Free tier allows 20 images per month, each up to 5MB. Files upload to their servers.

6. iLoveIMG

Best for: All-in-one image operations in one place.
The image counterpart to iLovePDF, iLoveIMG offers 30+ tools covering compression, resizing, cropping, format conversion, watermarking, and more. 31 million monthly users. Files upload to their servers and are deleted after processing.

7. Squoosh (by Google)

Best for: Maximum compression control for developers.
Squoosh is Google's browser-based image compression tool. It processes images locally (no upload), supports all modern formats including AVIF and WebP, and gives you granular control over compression settings. It's technical but powerful.

8. Remove.bg

Best for: Background removal with the best AI quality.
Remove.bg is the original and still the best AI background removal tool. Free tier gives you 50 preview-resolution removals per month. Files upload to their servers. The quality is excellent, especially for product photos and portraits.

9. Fotor

Best for: One-click photo enhancement.
Fotor has a strong AI-powered "one-tap enhance" feature that automatically improves colour, brightness, and sharpness. Good for quickly improving smartphone photos. Files upload to their servers. Free tier has watermarks on some exports.

10. ImageZen4u — Best for Privacy-Conscious Users

Best for: Image conversion and compression where files must never leave your device.
ImageZen4u takes a completely different approach: your images never leave your device.
