Image Format Converter

New free tool

Private Image Format Converter

Convert browser-readable images to WEBP, JPG, PNG, or AVIF with quality and optional max dimension controls. Files are processed locally, and unsupported formats are explained instead of uploaded.

Quick answer

An image format converter changes the encoded file type while keeping the visible image content.

This tool also offers quality, compression, and optional downscaling controls for smaller exports.

Best inputs for conversion

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.

Format notes

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.

Common format choices
Choose the output format based on where the image will be used.

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-perfect graphics matter.

Privacy and browser support
The browser does the decoding and encoding work locally.
Unsupported input files show a message when the browser cannot decode them.
WEBP and AVIF export availability is detected in the current browser before conversion.
Canvas export may strip metadata and turns animated images into a still frame.
Example
Upload a PNG screenshot, export it as WEBP at 86 percent quality, optionally cap the width at 1600 px, and download a smaller web-ready file.
Assumption
The browser can decode the source image and encode the selected output format. HEIC, TIFF, AVIF, and SVG behavior varies by browser.
Limitation
Conversion does not preserve animation, EXIF metadata, or every color-management detail, and very large images may exceed browser memory limits.

Frequently asked questions

Does this image format converter upload my file?

No. The image is decoded, converted, and exported in your browser. The current tool does not send the source image to a backend.

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.
