DocSlim

Features

One app for every upload requirement.

Government portals, exam forms, visa applications and job sites all have strict file rules. DocSlim handles them for you.

Scan a document

Point your camera at any paper document. Automatic edge detection finds the page, straightens it and cleans it up into a sharp PDF or JPG.

FAQ

Common questions

Are my documents uploaded anywhere?

No. All processing happens on your iPhone. Your photos, scans and PDFs are never sent to our servers or anyone else's.

How does "Compress to KB" work?

Enter the maximum file size your form allows, such as 50 KB. DocSlim adjusts quality and resolution to produce the best-looking file under that limit.

What's the difference between Crop, Fit and Stretch?

Crop fills the exact size and trims the edges. Fit keeps the whole image and adds padding where needed. Stretch fills the exact size without cropping, which may change the proportions.

Does it work without internet?

Yes. Because everything runs on your device, every tool works offline.

What do I get with Pro?

Pro lets you save and share the files you create, for ₹249 per year. You can try every tool and preview your results for free before upgrading.
