Squish: Image & PDF Tools

Devarsh Desai

About this app

Squish is a set of image and PDF tools for online forms, and it works completely offline. Your photos, documents and passwords stay on your phone and are never uploaded anywhere.

COMPRESS IMAGES TO ANY SIZE LIMIT
Form says "photo under 200 KB"? Pick the limit (20, 50, 100, 200, 500 KB or your own) and Squish finds the best quality that fits. No guessing with sliders, no trying again and again.
- Exact size targets for exam, job and government forms
- Compress up to 30 images at once
- Keeps the best quality possible and only shrinks dimensions when it has to
- Works with JPG, PNG, WEBP and HEIC photos

RESIZE & CROP
- Passport photo (3.5 x 4.5 cm), square, signature and document presets
- Your own size in pixels or centimetres
- Crop to the exact shape, then add a KB limit if the form needs one

IMAGES TO PDF
- Turn photos or camera scans into one PDF
- Put pages in any order, A4 or same-as-photo pages
- Up to 30 pages, sharp or smaller file

UNLOCK PDF
Tired of typing your PAN every time you open a bank statement or salary slip? Remove the password once and save a copy that opens instantly.
- Works with the password you already know; Squish never guesses or cracks passwords
- Capital and small letters are tried for you, so "abcde1234f" works for a PAN password
- Your original locked PDF is never changed

LOCK PDF
Add a password before you share ID copies, offer letters or statements.
- Use your PAN as the password with one tap, or set your own
- Strong AES-256 encryption that opens in any modern PDF reader
- Can also change the password of an already locked PDF

MERGE PDFS
- Join up to 20 PDFs into one, in the order you choose
- Password-protected PDFs can be unlocked right in the list
- Each page keeps its original size and rotation

PRIVATE BY DESIGN
Most online tools upload your files to their servers. Squish doesn't.
- 100% on-device processing, no uploads, works without internet
- No account, no sign-up, no ads, no tracking
- No storage permission: you choose exactly which photos and files Squish sees
- PDF passwords and PAN are never stored
- Your original files are never changed

Squish is made by an independent developer in India. Found a bug or have an idea? Email the address on this page. Every message is read.
