Frequently Asked Questions

How do I convert JPG to WebP and keep it under 20KB?+
Convert your JPG file to WebP using the free converter, then check the resulting file size. If it's still above 20KB, run it through the image compressor and lower the quality slider until it fits.
Does converting to WebP always reduce file size?+
Not always — it depends on the image content. WebP typically produces smaller files than PNG or JPEG at a comparable visual quality. For the smallest reliable file size, combine format conversion with the compressor's quality slider.
Is this tool really free with no upload limits?+
Yes. Conversion and compression both run entirely in your browser using the Canvas API — no files are uploaded to a server, so there are no size limits or sign-up requirements.
