About PDFTuck
PDFTuck is a small Android app for one job: getting a PDF under the size limit a form or portal asks for, on the phone, without uploading it.
Why it exists
Upload limits are everywhere: job portals, universities, government services, insurers. The usual advice is to upload the file to a website that shrinks it, pick a level, download it, check the size and try again.
PDFTuck turns that around. You type the limit. The app tries a few settings, measures the files it makes and keeps the best one that fits, and says plainly when a limit can’t be reached without making the pages unreadable.
Who makes it
PDFTuck is published by Karahoca Labs. The app’s name on Google Play is “PDFTuck: Compress PDF to KB”.

How we check what this site says
Every product statement on this site is checked against the app’s source code and its in-app text before it is published. Where the app’s behaviour depends on the document, the site says so instead of promising a result.
Comparisons with other tools use only those companies’ own websites, help pages and Google Play listings, with the date we checked them. If we couldn’t confirm something, we write “not verified” rather than assuming it’s missing.
There are no reviews, ratings or testimonials on this site, because we haven’t collected any.
