Compress Image to 15KB
15KB fields appear on application portals for signatures and small photos — tight, but workable once the image is sized sensibly. We compress the photo toward your target at the best quality that fits, never enlarge it, and always show the real final size — highly detailed photos may land slightly above very tight targets.

The 15KB workflow
Resize to the field's expected dimensions first (forms usually state them — 140×60 for signatures, 200×230 for photos), then compress to 15KB. In that order, quality survives; skipping the resize forces brutal compression instead.
Signature and photo fields
Exam and government portals pair pixel specs with KB caps precisely so uploads stay uniform — meet both numbers and the upload sails through validation.
