Compress photos to an exact size, convert formats and add watermarks — offline.
Big photos, small problems — fixed in a few taps.
PhotoKit shrinks your images to the exact file size you need (100 KB, 300 KB, 1 MB or any custom target), converts between JPG, PNG and WebP, resizes by pixels or percent, and stamps clean text watermarks — all on your device.
Built for the moments that matter: ID and exam uploads with strict KB limits, marketplace listings, faster sharing, tidier storage.
Why PhotoKit:
• Compress to a target size — pick a preset or type your own KB/MB
• Batch processing with live progress and before/after sizes
• JPG / PNG / WebP conversion and resize in one pass
• Text watermark with 9 positions, opacity, size and color controls
• Keeps EXIF data on JPEG output when you want it
• Works fully offline — your photos never leave your device
• No account, no sign-up, no storage permission needed
Your photos are processed locally. Nothing is uploaded, nothing is tracked.
