Frequently Asked Questions

How do I convert JPEG to PNG and keep it under 20KB?+
Convert your JPEG file to PNG 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 PNG always reduce file size?+
Not always — it depends on the image content. PNG is a lossless format — ideal for graphics, logos, and images that need transparency. 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.
