How to Compress a PDF for a Job or Government Portal

Portal upload fields usually state a maximum size and an accepted format right next to the button. Limits like 50 KB, 100 KB, 200 KB, and 500 KB are common, and different fields on the same form can have different caps, with the photo and signature often smaller than document uploads.

These limits change between recruitment cycles and between portals, so always trust the number shown on the official page over any general advice, including this guide. When in doubt, confirm on the portal itself before you submit.

Once you know the cap, compress your PDF to that target. KiloPDF searches across quality and resolution settings to land at or just under the size you ask for, so the upload field accepts it on the first try.

Pick the target that matches the field. If the form wants 100 KB, choose 100 KB rather than guessing. The result keeps the best quality that still fits the limit.

Application documents are sensitive: identity proofs, category certificates, mark sheets, and bank details. KiloPDF compresses them entirely in your browser, so these scans are never uploaded to a third-party server while you prepare your application.

Choose your file, set the exact target the portal asks for, and download. Repeat for each document, then upload them to the portal. Keep your originals in case a field later accepts a larger file.
