Convert images between formats
Drop any image, see what it really is, pick what you need. Converted on your device.

Converts images between JPG, PNG, WebP, GIF, BMP, TIFF, ICO and PDF, and reads HEIC, AVIF, JXL and SVG as input, and has ready-made pages for turning any image into JPG or PNG. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The size limit is your device’s memory, and phones hold less; give the page a short while after one visit to save itself for offline use, and then it works offline.

Free, no ads. Support StayPut
Open the network tab. Your files never appear in it.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
How it works
- Drop any images onto the page. Stayput reads each file and shows its real format, even if the extension is wrong.
- Pick the output format: type to search, for example "ico" or "pdf". Set the quality for JPG, WebP and PDF.
- Download the results one by one or as a zip.
In your browser, not on a server
Stayput first reads the opening bytes of each file, where every image format writes its signature, so it knows what the file really is whatever it is called. Your browser decodes JPG, PNG, WebP, GIF, BMP, AVIF and SVG itself; TIFF goes through UTIF.js, HEIC through the libheif WebAssembly decoder, and JPEG XL (or AVIF, in a browser without native support) through the Squoosh decoders, all served from this site and cached. The browser re-encodes JPG, PNG and WebP; PDF, ICO, GIF, BMP and TIFF files are written by small encoders in the page. Nothing here needs a server.
Compared with upload-based tools: Online converters upload your image, convert it on their machine, keep it for hours and cap you at a few files a day. This does the same conversion on your device, for as many files as your device’s memory can hold, with no upload to wait for.
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Which formats can I convert from?
Anything your browser can display: JPG, PNG, WebP, GIF (first frame), BMP, SVG and AVIF. HEIC and HEIF photos are decoded with a WebAssembly build of libheif (for a dedicated page, see the HEIC to JPG converter), and JPEG XL (and AVIF in older browsers) with the Squoosh decoders compiled to WebAssembly, so they work everywhere. To cut the background out of a photo, use the background remover.
Which formats can I convert to?
JPG, PNG, WebP, PDF (one page per image), ICO (a favicon or Windows icon with every size from 16 to 256 pixels), GIF (a still image, 256 colours), BMP and TIFF. Formats that cannot hold transparency fill it with the background colour you pick.
Just need JPG or PNG?
Use Convert any image to JPG or Convert any image to PNG. They run this same converter with the output already chosen and explain what each format does to quality and transparency.
Is JPEG the same as JPG?
Yes, they are one format with two spellings. Renaming a .jpeg file to .jpg changes nothing inside it; converting here saves a re-encoded copy. JPEG to JPG has the details.
How does it know what format my file is?
It reads the first bytes of the file, where every image format writes its own signature, instead of trusting the name. A photo called .jpg that is really HEIC, or a download called .png that is really WebP, is shown as what it is and converted correctly.
Why is WebP the smallest option?
WebP compresses photos about 25 to 35 percent smaller than JPG at the same visual quality and supports transparency. Every current browser displays it. Use JPG when you need to send the file to an older program.
What happens to transparency when I convert to JPG?
JPG has no transparency, so transparent areas are filled with the background color you pick (white by default). Convert to PNG or WebP to keep transparency.
Is anything uploaded?
No. Decoding and encoding happen in this browser tab. After one visit and a short wait this page works with your network switched off.

Compress & Resize Images
Make photos small enough to email or upload. Batch resize, set a quality, see the savings before you download.
Compress GIF
Make an animated GIF small enough for Discord, Slack, email or a web page. It is compressed on this device and never uploaded.
Compress PNG
Shrink PNG screenshots, logos and graphics while keeping them PNGs, transparency and all. Nothing is uploaded.
Remove EXIF Data
See what a photo reveals, then delete it. The image data is copied unchanged and only the metadata is removed; a sideways JPG is re-encoded only if Apply orientation is on.
