Compression Settings
Quick Compression Presets
PNG is a lossless format, so quality is applied as a reduced colour palette instead. For photos, JPG or WebP will always compress far more than PNG.
Image Resizer
Resize images to exact pixel dimensions or by percentage — client-side, instant.
HEIC to JPG Converter
Convert Apple HEIC photos to JPG instantly in your browser. No sign-up needed.
Resize Image to 20KB
Set a JPEG size target for a photo or signature, then check the result against your current portal requirements.

Reduce image file size while keeping the same dimensions

Choose a JPG or WebP output, leave Max width blank and start with a moderate quality setting. Check file size and preview fine text, edges and gradients. Lower the quality in small steps until the result meets your needs.

Choose the right tool for a strict limit

If you also need exact pixels, use the image resizer first. For a form that requires under 20 KB, try the 20 KB image resizer and confirm both dimensions and bytes before uploading.

Frequently Asked Questions

  • Will every compressed file be smaller?
    No. Results depend on the input, format and settings. Compare the displayed input and output sizes before downloading.
  • Does the quality setting affect PNG in the same way as JPG?
    No. PNG export does not use the lossy quality setting in the same way. For screenshots or artwork, compare the PNG size with a WebP copy.
