Image Tools

Resize, crop, compress and convert pictures, read their EXIF data, and generate QR codes and barcodes.

What to know about image tools

These tools work through the HTML canvas: the image is decoded into pixels, changed, and encoded again. That has one consequence worth knowing before you start — every save is a re-encode. Saving a JPEG at 90% quality twice is not the same as saving it once, and each round trip loses a little more detail. Work from the original rather than from a file you already exported.

The other thing a re-encode does is discard metadata. If a photo carried GPS coordinates from your phone, resizing or converting it strips them, which is usually what you want before posting a picture publicly. The metadata viewer will tell you what a file is carrying before you decide.

Two limits are worth stating plainly: background removal here keys on a colour you pick, so it works on flat studio backdrops and not on a person standing in a busy room; and very large photographs can exceed what a mobile browser will allocate for a canvas, particularly on iOS.

Frequently asked

Why did my transparent PNG come back with a black or white background?

JPEG has no alpha channel, so transparency has to become some solid colour when you convert. Keep PNG or WebP if you need the transparency; if you do want JPEG, the tool lets you choose the colour it fills with instead of guessing.

Can it remove the background from a photo of a person?

Not reliably. The background remover matches a colour you click and removes pixels close to it. On an evenly lit plain backdrop that works well; against a cluttered or shadowed background it will cut into the subject.

Does compressing lose quality?

JPEG and WebP compression is lossy by design, so yes, and the tool shows you both file sizes so you can judge the trade. PNG compression is lossless, which also means the savings are much smaller.
