JPG, PNG or WEBP โ up to 20 at once, everything happens in your browserWhat makes 300KB different from smaller targets
At 300KB, compression artefacts are rarely visible even on close inspection, which is exactly why visa and passport-style systems often choose it โ the photo has to look convincing at full size, not just pass an automated file-size check. If your target file is already under 300KB, this tool will simply confirm that instead of compressing it further and losing quality for no reason.
If you need an even sharper result for a physical print rather than an upload, consider skipping compression altogether and using our quality enhancer instead.
โ Frequently asked questions
Will 300KB compression be visible to the eye?
Usually not โ at this size the tool typically only needs a mild quality reduction, so most photos look effectively identical to the original.
Does this tool accept HEIC photos straight from an iPhone?
Most modern browsers can decode HEIC files directly; if yours doesn't, convert with our HEIC to JPG tool first.
Can I use this for a passport renewal photo?
Yes, as long as the photo itself already meets your country's passport photo composition rules โ this tool only handles the file size, not cropping to a specific photo standard.
