Why 20KB Is Such a Common Requirement
Indian government portals — from UPSC to GATE, SSC, banking exams, and state civil services — set strict file size limits on passport photos and signature uploads to keep their databases lean and their form processing fast. 20KB is the threshold they've converged on for signatures, and anywhere between 10KB and 20KB for candidate photographs. The frustrating part isn't the limit itself — it's that most image editing tools don't let you target a specific file size. You end up guessing, re-exporting, checking, and guessing again. PixSuite takes a target size as input and works backwards from there, adjusting compression parameters automatically until your image lands at or under 20KB while staying as sharp as possible.
Getting a Clean, Readable Image at 20KB
The challenge at very small file sizes is that standard compression artifacts become visible — blocky patches, color banding, smearing around edges. These are particularly noticeable in faces and text-based signatures, which are exactly what exam portals ask for. PixSuite's compression algorithm prioritizes edge sharpness and skin tone fidelity over even color distribution, which means your photograph or signature stays clear and readable even at 20KB. The output is a file that meets the portal's technical requirement and passes the visual quality check on the other end.
Compression Strategy FAQs
Which exams and portals require a 20KB image limit?
UPSC, GATE, SSC CGL, IBPS, SBI PO, and most state PSC portals commonly set 20KB as the upper limit for photo or signature uploads. Always check the official notification for exact specs.
What dimensions should the image be for exam portals?
Most exam portals specify dimensions separately from file size. Common requirements are 200x230 pixels for photographs and 140x60 pixels for signatures. Resize the image to the correct dimensions first, then compress to 20KB.
Can I compress a JPG, PNG, or WebP to 20KB?
Yes. The tool accepts all major image formats as input and outputs a compressed JPG at the target size.
Is the compressed image accepted by government portals?
The output is a standard JPG file. Whether it's accepted depends on the portal's specific requirements — always cross-check dimensions and format before uploading.
