How does the strict target KB slider prevent portal rejections?

Government portals like SSC, UPSC, and NTA reject files that exceed maximum limits even by 0.1 KB (e.g. 50.1 KB). LoomPDF's multi-pass compression algorithm guarantees the output file is strictly less than or equal to your chosen target KB limit without exceeding it.

How can I resize both Image and PDF in one single tool?

Upload your image (JPG, PNG, WEBP, BMP) or PDF document into LoomPDF Universal Resizer. The tool automatically detects the file type. Use the target KB slider or quick portal presets (20-50 KB, 10-20 KB, 100 KB, 200 KB) and click Compress to download your portal-compliant file instantly.

Does compressing a PDF to 100 KB or 200 KB reduce text legibility?

No. Our intelligent quantization engine optimizes high-resolution scans and raster elements while preserving crisp text legibility, candidate signatures, and official seals for government scrutiny.

What are the official file size limits for SSC, UPSC, and NTA exams?

SSC CGL/CHSL requires photos between 20-50 KB and signatures between 10-20 KB in JPEG format. UPSC allows photos up to 300 KB (40 KB recommended). NTA NEET and JEE require category certificates and marksheets in PDF format between 50-300 KB.

Is it safe to compress confidential marksheets and ID proofs on LoomPDF?

100% safe. All file processing runs locally in your device RAM memory using WebAssembly. No photos, marksheet scans, or confidential records are ever uploaded to any cloud server or database.

Frequently Asked Questions

Why does my photo get rejected by SSC or UPSC portals?

Government portals have strict automated validators. If a portal has a 50 KB limit and your photo is 50.1 KB or 50.05 KB, the portal throws a "File size exceeds limit" error. LoomPDF's strict algorithm ensures files stay safely below the threshold (e.g., 48-49 KB).

Can I convert an image into a PDF under 100 KB or 200 KB?

Yes. Select the PDF export format when uploading an image, and choose your desired target KB. The engine optimizes image quantization and creates a clean PDF wrapper under your limit.

Is it safe to compress confidential marksheets and identity proofs?

100% safe. LoomPDF executes all compression in your browser RAM using WebAssembly and HTML5 Canvas. Your files are never uploaded to any remote server.
