# Convert Image Format

Convert images between PNG, JPG, and WebP in your browser. Control quality and the background colour that replaces transparency. Free and private.

### Picking the right format for the job
Three formats, one decision: PNG is lossless and keeps transparency. JPG is small but cannot store transparency at all. WebP is smaller than both and still keeps transparency, at the cost of some older software refusing it. Almost every conversion question comes down to those three trade-offs.

Quality you actually control: For JPG and WebP the quality slider decides how much detail is discarded. The control greys out for PNG because PNG is lossless — a quality setting there would be a slider that does nothing, which is worse than no slider at all.

Transparency is an explicit choice: Converting a transparent image to JPG forces a decision, because JPG has no alpha channel. Rather than silently defaulting to black — which is what a surprising number of converters do — the background colour is a control you set. It greys out for PNG and WebP, which keep transparency.

Nothing leaves your browser: The encode runs locally on canvas. There is no upload, so no queue, no server-imposed size limit, and no copy of your file anywhere afterwards — which matters for client work and unpublished artwork.

### How to convert image format
1. Upload your image — Drop in a PNG, JPG, WebP, or SVG. It is read locally in your browser.
2. Choose the output format — Pick PNG, JPG, or WebP. The other controls enable or grey out to match what that format can actually do.
3. Set quality and background — For JPG and WebP, choose a quality level. For JPG, choose the colour that replaces transparency.
4. Download — Save the converted file — the extension follows the format you picked.

### When a format change is the fix
- Page speed: Move photographs off PNG and onto WebP or JPG.
- Preparing to edit: Convert to PNG before background removal or colour work.
- Upload requirements: Match whatever format a form or portal insists on.
- Opening stubborn files: Turn a WebP into something your software will actually read.
- Sending files: Get a large image down to an attachable size.

### Frequently asked questions
Q: Which format should I pick?
A: For a website, WebP almost always. For a photograph going to unknown software, JPG. For editing, archiving, or anything needing transparency and universal support, PNG. If you are unsure and it has transparency, do not choose JPG.

Q: Why is the quality slider greyed out?
A: Because you have PNG selected, and PNG is lossless — there is no quality level to set. The slider enables as soon as you choose JPG or WebP.

Q: Why is the background colour greyed out?
A: Because PNG and WebP both keep transparency, so nothing needs filling in. It enables for JPG, which has no alpha channel and must put something behind transparent pixels.

Q: Does converting improve quality?
A: No. Converting to a lossless format preserves what is already there, artefacts included; it does not repair them. Converting to a lossy format can only reduce quality. Neither direction adds detail.

Q: Can I convert SVG files?
A: You can upload an SVG and convert it to PNG, JPG, or WebP. Note the result is a raster image at the SVG's rendered size, so it stops being resolution-independent.

Q: Is anything uploaded to a server?
A: No. The whole conversion happens in your browser, so your file never leaves your machine.
