Hey everyone,
I recently built a PDF utility app with tools like PDF merge, convert, compress, image to PDF, etc.

One thing I focused heavily on was privacy. All processing happens directly on device in real time, so files are not uploaded to any server.

I’m currently looking for a few people to join the closed testing phase and share honest feedback about bugs, UI, speed, or missing features.

PDFTools on Google Play

Would really appreciate the help 🙌

Hey mods, thanks for the heads up! I think I may have missed the correct flair while posting. I’m just looking for a few genuine testers for my PDFTools app and would really appreciate any guidance on which flair/category fits best. Happy to edit the post accordingly. 🙂

Found out someone had been reposting my shots on Instagram without any credit and that was the last straw for me. Started looking for a watermarking app that didn't look ugly or take forever and tried a few but they either slapped a giant logo on my photo or made me pay just to change the font. So I just built my own solution and turned it into an app called StampIt. It lets you place a custom watermark anywhere on the photo, adjust opacity, size and position and batch stamp multiple photos at once. If anyone else has dealt with photo theft and wants to try it out - here is the link

Delivered a shoot to a client last year and three months later found one of my best shots on their homepage without any agreement or extra payment. Reported it and they just ignored me completely. After that I made it a rule to watermark every single photo before delivery including the previews. Tried a bunch of apps but most of them either stretched the watermark weirdly or buried the good features behind a subscription. Eventually built my own app called StampIt that lets you add a fully custom watermark, control the opacity and position exactly how you want it and batch process an entire shoot in one go. If you've been burned by something similar and want to try it just drop a comment below and I'll share the link!

The idea was simple: make PDF tools fast, clean, and unrestricted — no annoying ads, no “2 tasks per day” limits, and no broken conversions.

Current features include:
• PDF to Word/Image
• Merge & Split PDFs
• OCR
• Compress PDFs
• Fast local processing for many tasks

I’m mainly looking for feedback on:
• UI/UX
• Performance
• Bugs/crashes
• Features you’d actually use
