About the 30KB image
30KB gives a little more room than 20KB, so photos keep more facial detail. It is a frequent ceiling for passport-style pictures on application portals.
How to compress an image to 30KB
- Select your image. JPG, PNG, WebP and iPhone HEIC all work, and you can pick several at once.
- Check the size. The box is already set to 30. Change the number if your form says something different.
- Press the green button and download a JPG under 30 KB, or one ZIP for many files.
Compress mode keeps the best quality that still fits under your limit.
Where you need a 30KB image
Passport-style photos
Fits many online application photo fields where the limit is a few tens of KB.
Seals and stamps
Stamps and seals with fine lines need a bit more room than a signature.
Entrance test forms
Candidate photo and signature uploads often have separate small limits.
Online ID checks
Selfie crops for quick verification upload faster at this size.
What to expect at 30KB
Faces at 30KB are usually clear at about 400 to 500 pixels tall. Text on documents may need a higher limit such as 100KB.
30KB image FAQ
Is 30KB enough for a scanned certificate?
Usually not for small printed text. Photos of documents need 100KB to 200KB; keep the 30KB setting for faces and signatures.
How can I get better quality at 30KB?
Crop out empty background before compressing. Fewer pixels to encode means more of the 30KB goes to your face.
Will the tool change my photo's dimensions?
Only when lowering quality alone cannot reach 30KB. If the quality drop is enough, the width and height stay untouched.
Is my photo uploaded when I compress it to 30 KB?
No. The 30 KB resizing runs inside your browser, so your picture never leaves your device. No signup, no watermark.
