All Free Image Tools

Which tool do you need?

The 14 tools here fall into four groups. Every one of them runs inside your browser: the site has no backend, so your file is decoded, processed and re-encoded on your own device and never travels anywhere. That also means there is nothing to sign up for and no queue to wait in — the work starts the moment you drop a file in.

Optimize — make the file smaller or a different shape

Start here if the problem is the file itself rather than the picture. The compressor re-encodes a JPG, PNG or WebP at a quality you choose, which is usually enough to cut 60–80% off the size before anyone can see a difference. The resizer changes pixel dimensions with the aspect ratio locked by default. The converter moves between JPG, PNG and WebP — worth doing when you need transparency (PNG) or the smallest file for a web page (WebP). The deblur and enhance filters sharpen and denoise a photo that came out soft.

AI & Art — change how the photo looks

These apply a style rather than fixing a file. Photo to anime, photo to cartoon and photo to pencil sketch each run a different pixel pipeline over your image, and style transfer applies a painterly treatment. They work best on a clear, well-lit subject and, like everything else here, they never upload the photo — useful if the subject is a person.

Analyze — get information out of an image

Nothing here changes your picture. The QR code scanner reads a code out of a screenshot or a photo when your phone camera is not an option. The colour palette detector pulls the dominant colours out of an image, which is the fastest way to build a palette from a reference. The tampering detector runs error-level analysis to show where a JPEG has been re-saved inconsistently — a hint that a region was edited, though not proof on its own.

Capture — turn photos into a finished document

The document scanner straightens a photographed page, corrects the perspective and thresholds it to clean black and white, so a phone snap reads like a scan. The panorama stitcher blends several overlapping photos into one wide image. Because both run locally, scanned documents — usually the most sensitive thing anyone puts through a tool like this — stay on your device.

If you know the exact task

The tools above are general-purpose. If you already know the specific thing you need — compress a JPG to a target size, resize for an Instagram post, convert PNG to WebP — the use-case index has a focused page for each one, with the right settings already explained. The guides cover the underlying questions, like which format to choose for the web and how much compression is too much.
