Upload rejected because the file is too big? Make photos, signatures and PDFs the exact size in KB. Free, works offline, and your files stay on your device.

Online form rejected your photo because it's too big? DocSlim makes your photos, signatures and documents the exact file size an upload page asks for, in a few taps.

COMPRESS TO EXACT KB Pick a photo and choose a target like 20 KB, 50 KB or 100 KB, or type your own. DocSlim shows the final size before you save, so you know it fits the limit.

READY-MADE SIZE PRESETS One tap for common upload limits: • Photo under 50 KB or 100 KB, keeping its original shape • Square photo: 600×600 px, under 240 KB • Signature: 140×60 px, under 20 KB • PDF under 1 MB, or a small PDF under 200 KB

SCAN DOCUMENTS Scan letters, receipts, notes and printed pages with your camera. Automatic edge detection captures each page when you hold steady. Save as a PDF or JPG.

PDF TOOLS • Compress PDF to fit upload limits • Merge several PDFs into one • Images to PDF, with pages in any order • Edit PDF text: fix a typo or fill in a blank

RESIZE PHOTO Set exact width and height in pixels, choose crop, fit or stretch, and keep it under a target size.

PRIVATE BY DESIGN • Everything is processed on your device • No account or sign-up needed • Works offline • Optional Face ID lock to protect your saved files

All your files are kept in one place, ready to share to WhatsApp, Mail, the Files app or any upload page.

Note: Upload limits differ between websites, so always check the size rules of the page you are uploading to.
