💡 Tips for Best Results
Frequently Asked Questions
My photo is 3MB. Can I really compress it to 20KB?
Yes. Standard smartphone photos are 3–8MB. Our tool strips EXIF metadata, reduces colour depth, and re-encodes the image to reliably reach 20KB while keeping the subject clear.
Will my signature still be readable at 20KB?
Yes. We use a sharpening filter specifically designed for high-contrast black-on-white content like signatures so every stroke remains visible.
What image formats can I compress?
We support JPG, JPEG, PNG, WebP, and BMP. The output is always a JPG for maximum compatibility with portal upload fields.
Does this tool remove EXIF data from my photo?
Yes. EXIF metadata (GPS, camera model, timestamps) is stripped during compression, which also improves privacy.
Is there a limit to how many images I can compress?
No. All tools on Utilifyx are completely free with no daily limits, no login required, and no file count restrictions.
Can I compress a group photo to this size?
A group photo can be compressed to 20KB, though some quality reduction is expected. For best results, we recommend using individual photos for official submissions.
