Set Target KB Limit or Range
Specify the maximum allowed file size (e.g., 50 KB) or set a required window (e.g., 10 KB to 20 KB).
Verify & Download
Check that your exported file satisfies your target dimensions and size limits, then download your ready image.

Frequently Asked Questions
Common questions about resizing ID photos and signatures to exact KB limits.
How does the tool guarantee my photo fits inside the requested KB limit?
Pinatool automatically tests multiple quality levels directly in your browser to find the highest possible visual clarity that stays strictly below your maximum KB limit (or inside your chosen min–max KB range).
Can I resize a signature to between 10 KB and 20 KB?
Yes. Choose the "Official Signature (Small)" preset or switch to "Range" mode and enter 10 KB as minimum and 20 KB as maximum. The compliance indicator immediately confirms whether the exported file lands inside your target range.
What happens if an image cannot fit under the KB limit at full resolution?
If you enable "Automatically scale down resolution", the tool adjusts the dimensions just enough so the file meets the KB limit while staying crisp and readable for portal submission.
Are my confidential ID photos or signatures uploaded to any server?
Never. Government ID photos, passport headshots, and handwritten signatures are sensitive personal data. Pinatool runs 100% locally in your browser memory—nothing is ever sent to or stored on remote servers.
Which formats are supported for official portal submissions?
You can export your optimized photo or signature as JPEG (the standard required by most government and exam portals), lossless PNG (ideal for sharp signature lines), or modern WebP.
