Modernize legacy JPEG photography

JPG has served as the default image format for decades, but modern formats like WebP offer superior compression ratios and sharper detail retention at lower byte weights.

Converting your JPG image library to WebP reduces page load times, saves cloud hosting bandwidth, and improves Google PageSpeed scores.

  • To WebP: Generates lightweight modern web assets with up to 35% smaller file sizes.
  • To PNG: Converts JPEG photos into an uncompressed raster bitmap for lossless editing in photo applications.
  • Zero Upload Latency: Local WebAssembly decodes and re-encodes images instantly in browser memory.

Clear answers

Frequently asked questions

Should I convert my JPG files to PNG or WebP?

Choose WebP if you want the smallest possible file sizes for web publishing (typically 25–35% smaller than JPG). Choose PNG if you need lossless output for editing or archiving.

Does converting JPG to PNG make the image transparent?

Converting to PNG creates a container capable of transparency, but it does not retroactively remove solid backgrounds already encoded into the source JPG. To remove backgrounds, use our Remove Background tool.

Are my JPG files uploaded to your server?

Never. Conversions run locally inside your browser using multi-threaded WebAssembly. No image data is ever transmitted over the network.

Can I convert multiple JPGs at once?

Yes, upload up to 50 JPG files simultaneously. You can download converted images one by one or all together as a single ZIP.
