Image Format Converter
Convert JPG, PNG, and WebP images in your browser with quality controls and transparent PNG/WebP handling.
Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint. TOOLGRID measures tool usage, not the content you enter.

Browser-basedWhat this tool does
Browser-local image format converter for PNG, JPG/JPEG, and WebP. Batch select images, choose output format and quality, preview, and download.
Use it when a CMS, email tool, documentation site, or design handoff requires a specific image format. PNG can retain transparency, JPEG uses a chosen opaque background, and WebP is a modern option; none is guaranteed to be the smallest for every source.
Files are decoded in the current browser tab, re-encoded in memory, and downloaded locally. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint. Browser-local processing avoids a TOOLGRID upload path, but it is not a blanket security guarantee.
What you can do with this tool
Turn WebP assets into PNG or JPEG when a CMS, email editor, or document workflow does not accept WebP uploads.
Convert supported images to PNG when transparency must be preserved for icons, interface screenshots, overlays, or documentation.
Convert PNG or JPEG source images to WebP before publishing, then use Image Optimizer if you need additional resizing.
What to check before relying on the result
- Animated inputs are flattened to one decoded frame and color profiles can be normalized by Canvas.
- Re-encoding can increase file size; compare the actual output and keep the original until checked.
How to use
- 1
Drop one or more JPG, PNG, or WebP images into the workspace.
- 2
Choose PNG, JPEG, or WebP output. Adjust quality for JPEG/WebP and set a background color for JPEG output.
- 3
Review the preview, dimensions, and file sizes, then download each converted image.
Use Cases

Tips & Tricks
Converting a lossy JPEG to PNG preserves the current pixels, but it cannot recover detail removed by the original JPEG compression.
JPEG cannot store transparency. Transparent PNG or WebP pixels are flattened onto the selected background color before export.
Browser Canvas export captures a still frame. It is useful for static conversion, not for preserving animated WebP, GIF, AVIF, or APNG sequences.
FAQ
Are my images uploaded?
Conversion happens in the current browser tab with Canvas. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Which formats can I export?
PNG, JPEG, and WebP. The tool verifies that the browser actually encoded the requested format instead of silently falling back.
What happens to EXIF metadata?
Canvas re-encoding usually removes metadata. Use EXIF Cleaner when metadata inspection and removal is your main goal.
