Image tools

A PDF you upload is a document a stranger's server briefly holds. A photograph you upload is that, plus a set of coordinates accurate to a few metres, the make and model of your phone, its serial number in many cases, and the exact second the shutter opened.

None of that is visible in the picture. It sits in a metadata block called EXIF, written automatically, and it travels with the file through email, messaging apps and any site that stores originals. Reading your own photos is usually the moment this stops being abstract.

Every tool here redraws your image through a canvas, and a canvas holds pixels and nothing else. The metadata does not survive the trip. We did not build that in; it falls out of how the tools work.

Making files smaller

Resize is almost always the right first move: halving the dimensions removes three quarters of the pixels with no visible artefacts. Compress then trades quality for size with a slider, showing the saving as you drag. Doing both, in that order, is how a 8 MB phone photo becomes a 200 KB web image.

Changing format and shape

Convert moves between JPG, PNG and WebP — and warns you before transparency is lost. Crop cuts to a square or a standard ratio, which is what you want for an avatar or a thumbnail. Rotate and flip fixes photos that look upright on your phone and sideways everywhere else.

Before you publish

Remove EXIF shows what your photo reveals and strips it. Watermark adds a credit line with a live preview. Favicon generator turns one picture into every icon size a website needs, including a real multi-size .ico.

One architecture

Every tool decodes your image with the browser's own decoder, works on a canvas, and re-encodes with the browser's own encoder. No library is downloaded for the image work, no server is involved, and the tools keep working if you disconnect from the internet after the page has loaded.
