JPEG + Tiny + 640px for strict 30KB limits

Compress Image to 30KB | MiniPx — Free, Fast & Private

Some government forms and exam portals require images under 30KB — particularly for signature uploads and smaller ID photos. MiniPx helps you hit this strict target reliably.

The formula for under 30KB: JPEG format, Tiny preset, 640px max width. This produces files of 15-40KB for most photographs. For signatures, results are typically 5-20KB.

If 640px Tiny still produces files over 30KB (rare but possible with very complex images), reduce width to 480px. At this dimension with Tiny compression, virtually any image compresses below 30KB.

The quality at 30KB is perfectly acceptable for ID photos on form submissions and digital signatures. These images are displayed at small sizes on forms, so the visual impact of compression is minimal.

MiniPx shows the exact size after compression so you can verify compliance before submitting your application.

How it works

Upload image: Add the photo or signature you need under 30KB.
Set JPEG + Tiny + 640px: This combination reliably produces files under 30KB.
Check the size: Verify the compressed size is under 30KB. Reduce to 480px if needed.
Download: Save and upload to your form or portal.

Frequently asked questions

What settings get an image under 30KB?

JPEG format, Tiny preset, 640px max width. If still over 30KB, reduce to 480px width. This works for virtually any source image.

Will a 30KB image be blurry?

At 640px, a 30KB JPEG is clear enough for form submissions and ID purposes. It will not look as sharp as the original, but is perfectly usable for government portals and exam applications.

Which forms require under 30KB?

Some SSC signature uploads (10-20KB), certain state PSC exam portals, and specific government agency forms. Always check the exact requirement on your specific form.

Is my photo private?

Yes. Everything processes in your browser. Your photos and signatures are never uploaded to any server.
