Non-Destructive Byte Calibration for Certificates & Visas

Artificially enlarging a 600 × 600 px photo to 3000 × 3000 px just to push its file size over 100 KB breaks portal pixel limits and makes text fuzzy. PixelKit leaves your pixel dimensions untouched while calibrating the encoded JPEG byte stream directly.

Need strictly **under** 100 KB (e.g., `95 KB`) vs **above** 100 KB (e.g., `115 KB`)? Adjust the Custom KB box in Stage 3 by a few kilobytes to sit comfortably inside your portal’s exact window.

Exact Pixel Preservation

Keeps mandatory 420×540, 390×567, or 800×400 px dimensions intact while boosting KB.

PDF Output Available

Need a 100 KB–200 KB PDF certificate instead? Switch Stage 1 output to PDF.

100% Private Documents

Marksheets, caste certificates, and visas never touch external servers.

Frequently asked questions

How do I increase a 40KB JPG to above 100KB (e.g., 120KB) for a minimum-100KB portal?
Simply type 120 into the Custom KB field in Stage 3 while Exact Size Mode stays active—PixelKit outputs an exact ~120 KB file safely above the 100 KB minimum.
What if my portal cap is 50KB to 100KB max?
Type 90 in Custom KB (or switch to "Min–Max Range: 50 to 100 KB") so the file lands around 85–95 KB without crossing 100.0 KB.
Can I batch-increase multiple certificate pages to 100KB?
Yes! Drop multiple files at once and download each calibrated image individually or as a single ZIP.
Does this work offline on mobile and desktop?
Yes—once loaded, PixelKit processes everything locally in your browser without sending a single byte over the internet.
