Browser-Side Image Format Converter
Convert browser-readable images to WEBP, JPG, PNG, or AVIF with quality and optional max dimension controls. Processing is handled in the browser for this tool based on the current public implementation.
An image format converter changes the encoded file type while keeping the visible image content.
This tool adds destination presets, browser support checks, quality controls, transparency notes, and optional downscaling.
Use browser-readable images
Common JPG, PNG, WEBP, GIF, SVG, BMP, AVIF, HEIC, and TIFF support depends on the browser you use.
Choose format by destination
Use WEBP or AVIF for web size, JPG for compatibility, and PNG when lossless transparency matters.
Drop image here or click to upload
Try any browser-readable image file. Unsupported formats will show a message.
Max file size: 25MB
No image uploaded
Pick a practical starting point for web delivery, compatibility, transparency, or AVIF testing. You can fine-tune the output after applying it.
Checking browser export support.
Keep this off for a pure format conversion, or turn it on to downscale large images while converting.

WEBP is usually a good web default, JPG is broadly compatible, PNG is lossless, and AVIF depends on browser support.
Animated GIFs and animated WEBP files are converted as a still frame because canvas export is static.
Canvas export may remove metadata such as EXIF orientation, camera info, or embedded color profiles.
Format guide
Choose the output format by destination
Format conversion is not the same as compression. Pick the format for compatibility, transparency, browser support, or delivery quality, then resize or compress only if the final file still needs it.
WEBP for web pages
A strong default for product images, blog images, screenshots, and landing page visuals.
JPG for compatibility
Useful for older systems, email attachments, marketplace uploads, and photo sharing.
PNG for lossless graphics
Best when transparency, sharp UI screenshots, logos, or pixel-sharp graphics matter.
AVIF for modern web tests
Worth testing when target browsers support AVIF and smaller web assets matter.
Operation order
Convert, then resize, then compress when needed
Batch roadmap
Keep single-file conversion fast, then add batch carefully
Expecting animation to survive
Canvas export creates a still image. Animated GIF, animated WEBP, and multi-frame files lose animation in browser conversion.
Using JPG for transparency
JPG does not support transparency. Choose PNG or WEBP when transparent backgrounds need to remain transparent.
Assuming every format is supported
HEIC, TIFF, AVIF, and SVG support varies by browser. Unsupported files should be converted with desktop tools first.
Suggested workflow
Convert before final optimization
Use this path when you need the right image format, final dimensions, and a lighter file for publishing.
Guides and examples
Use this tool in a real workflow
How is the image converted?
The current public implementation is designed to decode, convert, and export the image in the browser. Avoid using sensitive images unless you have reviewed the implementation.
Which input image formats are supported?
The tool accepts image files and tries to decode them with your browser. JPG, PNG, WEBP, GIF, SVG, BMP, AVIF, HEIC, and TIFF support depends on the browser. Unsupported files show a clear message.
Which output formats can I export?
The tool can export PNG and JPG in modern browsers, and it detects whether WEBP or AVIF export is available before enabling those options.
Can I adjust image quality while converting?
Yes. JPG, WEBP, and AVIF exports include a quality slider. PNG export is lossless and does not use the quality slider.
Will animated images stay animated?
No. Browser canvas export creates a still image. Animated GIF or animated WEBP files are converted from the decoded still frame.
Does conversion keep metadata?
Usually no. Canvas export may remove EXIF data, camera metadata, embedded profiles, and animation details.
