Are my PNG files uploaded to any server?
No, all conversions occur completely client-side in your browser using the HTML5 Canvas API.
A fast, step-by-step walkthrough to transform high-resolution PNG images into lightweight JPGs with zero uploads.
PNG is a lossless format great for graphics with transparent backgrounds, but photo file sizes can be 5 to 10 times larger than JPG. Converting to JPG makes web pages load faster and saves storage.
JPG does not support transparency. Transparent areas in your PNG will be automatically filled with a clean white background.
Drop your PNG files into the converter area.
Select 90% for high detail or 75% for lightweight web images.
Instant conversion locally in your browser. Download individually or as ZIP.

Recommended tools for this guide:
Stitch lossless PNG frames into an animated GIF while preserving crisp edges, alpha channels, and pixel-perfect detail. Built for UI mockups, game sprites, icon sequences, and pixel art where JPEG compression would muddy lines or drop transparency.
Export the first frame of an animated GIF as a lossless PNG still with transparency preserved. Ideal for design comps, thumbnails, icons, and editing pipelines that need a crisp single image — not a full frame zip.
Save the first frame of an animated GIF as a lossy JPEG still for documents, email, and lightweight web thumbnails. JPEG drops transparency for a solid background and typically produces a smaller still than PNG when alpha is not required.
