StackTools
Private PDF and image tools that never leave your browser
A free, private alternative to upload-based PDF and image suites. StackPDF: 34 tools to merge, split, compress, convert, OCR, redact, sign, and protect PDFs. StackImage: 18 tools to compress, convert (including HEIC), crop, remove backgrounds, and upscale - all in the browser. No account. Files never leave your device.
Hey Product Hunt - Jayant here, maker of StackTools.
I got tired of uploading contracts, IDs, and photos to random converter sites. So I built a suite that never takes the file: everything runs in your browser.
Two live apps today:
• StackPDF — 34 tools (merge, split, compress, convert, OCR, redact, sign, encrypt)
• StackImage — 18 tools (compress, HEIC, crop, remove background, on-device upscale)
No account. No upload API. After the first visit, many tools keep working offline.
I’d love feedback on:
1. Which tool you’d use this week
2. Anything that felt slower or less honest than a cloud suite
3. What you’d add next (docs? video? something else?)
Happy to answer anything about how the on-device engines work.
