Convert an image
PNG, JPG, WebP, GIF, BMP, TIFF and ICO — converted on your device, never uploaded.
How it works
Three steps, and nothing leaves your device.
-
1
Choose your image
Drop in a PNG, JPG, WebP, GIF, BMP, AVIF, SVG, ICO or iPhone HEIC file. Nothing is sent anywhere — the file is read straight into the page.
-
2
Pick the output format
WebP for the smallest file, JPG for universal compatibility, PNG for lossless quality with transparency — or GIF, BMP, TIFF and ICO when something specific needs them. Each choice explains itself as you pick it.

Download the result
The converted file is built on your device and saved straight to it.
Which format to choose
- WebP is almost always the right answer for the web. It compresses roughly 25–35% smaller than JPG at the same visible quality, and unlike JPG it supports transparency. Every current browser reads it. The one place to avoid it is a file you will hand to someone else to open in older desktop software.
- JPG is the safe default for photographs you will share. Every device, every email client and every ancient piece of software opens a JPG. It has no transparency and it is lossy, so avoid re-saving the same JPG repeatedly — each round trip discards a little more detail.
- PNG is for graphics, not photographs. It is lossless, which is exactly right for screenshots, logos, diagrams and anything with sharp edges or flat colour. Used on a photograph it produces a file several times larger than a JPG with no visible benefit.
- GIF is limited to 256 colours. That is the format, not the tool: a photograph converted to GIF will visibly band, because every colour in it has to be mapped onto a 256-entry palette. Transparency is on or off with no partial levels. It remains useful for flat graphics and for anything that has to work in very old software.
- BMP is uncompressed, so expect large files. A 12-megapixel photo becomes roughly 36 MB. It is worth choosing when some older Windows program or an embedded device refuses everything else — never for the web.
- TIFF is what print and scanning workflows expect. Lossless and uncompressed, so the files are large, but it is the format publishers and document systems ask for. Note that most browsers cannot display a TIFF, so it is a delivery format rather than a working one.
- ICO packs several sizes into one file. Choosing it produces 16, 32, 48, 64, 128 and 256 pixel versions in a single icon, which is what a
favicon.iconeeds. Start from a square image: anything else gets squashed into a square, since icons are not allowed to be rectangular. - Converting to a lossless format will not recover lost quality. If your source is a JPG, the detail that JPG compression discarded is gone. Converting to PNG or TIFF afterwards preserves what remains at a much larger file size — it does not restore anything.
Frequently asked questions
Which formats can I convert between?
Output can be PNG, JPG, WebP, GIF, BMP, TIFF or a multi-size ICO icon. Input additionally accepts AVIF, SVG and iPhone HEIC files. AVIF output is offered only on browsers that can encode it.
Is there a file size limit?
No. The conversion runs on your device, so there is no upload and no server-side ceiling. Very large images are limited only by your device's memory.
Are my images uploaded?
No. This tool never sends the file anywhere. You can confirm it by opening your browser's network tab while converting, or by disconnecting from the internet after the page loads — the conversion still works.
Does converting to JPG lose transparency?
Yes. JPG has no transparency channel, so transparent areas are filled with white. Use PNG, WebP, GIF or TIFF if you need to keep transparency.
