Image Format Converter
Convert between PNG, JPEG and WebP — plus SVG/GIF/BMP — in your browser
What Is an Image Format Converter?
An image format converter changes a picture from one file type to another so it works everywhere you need it. Websites, editors, printers and messaging apps each favor their own formats: a PNG logo looks crisp but bloats a page, a JPEG photo cannot keep transparency, and a vector SVG cannot be pasted into a Word document as a normal image. This tool converts between PNG, JPEG and WebP, and rasterizes SVG, GIF and BMP into pixel images, entirely inside your browser with no upload. When a transparent image becomes a JPEG, you pick the background color that fills the empty areas instead of ending up with an ugly black box. Batch mode converts whole folders of mixed formats in one pass. It is aimed at web designers, shop owners, students and office workers who juggle image formats daily.
What this tool can do
- Convert between PNG, JPEG and WebP in both directions, with a quality setting for lossy targets
- Rasterize SVG logos and illustrations into sharp PNG or JPEG pixels at your chosen size
- Turn animated GIFs and BMP files into standard web-friendly formats
- Fill a chosen background color when converting a transparent PNG to JPEG — no black rectangles
- Process whole batches of mixed-format images in a single run
- Compare the file size before and after, so you can pick the format that really saves space
When you'll use it
- Converting a screenshot with small text to PNG so the lettering stays crisp
- Switching site images to WebP for faster pages while keeping a JPEG fallback
- Turning a vector logo into a raster image for documents and social profiles
- Shrinking a camera-phone image to a lighter format before emailing it
- Preparing graphics for a tool or system that only accepts one specific format
Privacy and limits: conversion happens locally in your browser with Canvas — images never leave your device, nothing is uploaded, and no account is required. Animated GIFs are captured as a still frame rather than kept animated, and formats browsers cannot decode at all (such as HEIC, AVIF or TIFF) are handled by the separate cloud converter, which runs the same job on a server.
The conversion matrix that matters
- PNG to JPEG flattens transparency onto white; JPEG to PNG never recovers quality already lost.
- WebP sits between: about thirty percent smaller than JPEG at similar quality, supported everywhere modern.
- Animated sources convert to their first frame unless the target supports animation too.
Convert for compatibility, not just size
Five formats, one tool
Convert between PNG, JPEG and WebP, and rasterize SVG, GIF and BMP into pixel images. Vector logos and clip art become ordinary files that paste into any document.
Fill the empty pixels
A transparent PNG turned into JPEG needs a solid background, so you pick the fill color first. The preview shows a checkerboard behind transparent areas so nothing surprises you.
Whole folders at once
Drop a mixed folder of JPG, PNG, GIF, BMP and SVG files and convert them all to one target format in a single run. Every output keeps its matching extension.
Frequently asked questions
Are images sent to a server during conversion?
No. Conversion runs entirely in your browser with the Canvas API — no upload, no sign-up, no watermark and no daily limit.
What happens to transparency when I convert to JPEG?
JPEG has no alpha channel, so transparent areas are filled with the background color you pick (white by default). Convert to PNG or WebP instead to preserve transparency.
Can it convert HEIC or AVIF?
Only if your browser can decode them, which most cannot. Because conversion uses the browser’s native image decoder, unsupported inputs like HEIC will not load. PNG, JPEG, WebP, GIF, BMP and SVG work everywhere.
