Why Compress to 10KB?
A 10KB limit is the tightest constraint you will realistically encounter, and it appears almost exclusively on signature-scan fields and micro-avatar uploads. Indian competitive-exam portals such as UPSC, SSC, and IBPS often require scanned signatures between 4KB and 10KB. Many insurance claim portals and internal HR onboarding systems also use a 10KB cap for tiny verification images — a small headshot or initials icon stored in a legacy database column. At this extreme budget, every pixel counts: SizeSnap's binary-search algorithm allocates the entire 10KB to stroke clarity or facial features, avoiding the wasteful guesswork of manual quality sliders.
Tips for Compressing to 10KB
Scan signatures in grayscale at 150 DPI for the best clarity-to-size ratio at 10KB.
Crop as tightly as possible — even a few pixels of extra whitespace waste bytes at this size.
Use JPEG format; PNG lossless encoding cannot produce usable results at 10KB for photographic content.
