Why do government recruitment portals reject candidate photographs?

Portals reject photos if the file size falls outside the permitted threshold (such as less than 20KB or over 50KB), if the pixel dimensions deviate from 3.5cm x 4.5cm, or if the background is patterned rather than white. PortalResizer enforces strict dimension and byte targets to eliminate rejections.

How does PortalResizer keep photos sharp during compression?

PortalResizer uses binary-search canvas quantization that reduces high-frequency background noise while preserving sharp structural facial contours, avoiding pixel blur.

Can I compress PDF documents on PortalResizer?

Yes. PortalResizer provides dedicated in-browser PDF tools to compress, merge, split, rotate, and watermark PDF documents under strict size limits like 100KB or 200KB.

Does PortalResizer work on mobile phones?

Yes, PortalResizer is fully responsive and optimized for touch devices on Android (Chrome) and iOS (Safari), allowing candidates to format documents directly from mobile cameras.

Frequently Asked Questions

How do I reduce an image size to 20KB or 50KB online?

Upload your photograph above, choose your target preset (such as MPSC Photo 20KB–50KB or UPSC Signature 10KB–20KB), and click Resize & Compress. The algorithm quantizes pixels in-browser in milliseconds without server transmission.

Are my photos, signatures, or documents uploaded to any server?

No. PortalResizer runs 100% client-side inside your browser via HTML5 Canvas and WebAssembly. Your personal photos, signatures, and IDs never leave your computer or smartphone.

Why do government recruitment portals reject uploaded photos?

Portals reject files when the byte count is even 1KB over the ceiling (such as 51KB when the max is 50KB), if dimensions don't match 3.5cm x 4.5cm, or if ink contrast is dull. PortalResizer automatically locks both byte-size and dimensions.

How does PortalResizer preserve image sharpness under extreme compression?

Our binary search compression adjusts discrete JPEG quantization tables to strip invisible high-frequency noise while preserving high contrast edges across facial contours and signatures.

Can I compress and merge PDF documents here?

Yes. Explore our PDF Tools Hub to compress PDFs under 100KB/200KB, merge multiple certificates, split pages, and convert PDF to images in-browser.
