Tools for photos: crop, compress, QR, watermark

Crop, resize, rotate, compress, watermark, merge, split, passport size, signature and QR. Most studios run locally.

Start with crop or resize if the shot is for a social slot or a document. Passport size is a dedicated canvas (35×45 mm / 2×2 in); do not guess with a free crop if the agency is strict.

Compress to JPEG, WebP or AVIF when email or a CMS rejects the original. Quality slider first, then compare. PNG to JPEG drops transparency onto a background. Watermark and signature are separate studios so a mark does not bake into the compress step by accident.

The parser is the exception: it fetches a page you name and lists images. Everything else reads the file in the tab. QR codes cover URL and Wi-Fi so a printed poster does not need a typed password.

A photo job is rarely one action. You may pull files from a page, download one URL, mirror, correct, crop, rotate, make a passport frame, sign, watermark, compress, resize, build a QR, merge, or split. This page is the index of that set. Each converter opens one of those studios in the mode the task names, instead of making you hunt the control.

FAQ

Which studios upload?

The image parser requests the URL you enter. The rest process files in the browser.

JPEG or WebP?

JPEG is universal. WebP is smaller at similar quality if the destination accepts it.

Passport DPI?

Confirm with the agency. The studio exports the pixel size; print shops still ask for DPI.
