ShrinkRay converts Word, PDF, Excel and 9 more file types into lean, AI-ready Markdown, right on your PC. Documents shrink 60–90%, so you fit 3–10× more into every ChatGPT or Claude conversation.
Free for personal use · No account · No upload · Works offline · Windows 10/11 & macOS
Most of what an AI reads in your files is not your content. It is XML wrappers, style definitions, metadata and markup noise. That noise burns your usage limits on the $20/month plan you already pay for, crowds out the context the AI needs to give good answers, and bills real money on API accounts.
One tool, four kinds of users. Same app, same privacy, different license.
Research, school, side projects, personal finances. Stop hitting "conversation too long" walls and stretch every message of your ChatGPT Plus or Claude Pro plan. Every feature included, nothing held back.
Download free →Realtors, attorneys, consultants, accountants. Your contracts and client documents should never touch a random web converter. ShrinkRay processes everything on your machine, so confidential stays confidential.
Get licensed →Up to 10 seats for one flat price. Brokerages, law offices, agencies. Everyone converts the same way, batch folders of case files into single "context packs" and share AI-ready documents in seconds.
Cover your team →You pay $25–60 per seat monthly for AI tools. One dollar makes those seats meaningfully more efficient and keeps sensitive documents off third-party servers. Silent MSI-style deployment, annual invoicing, W-9 on request.
Talk to us →Every tier includes the full app. Paid licenses fund updates as AI keeps changing, and follow one rule: you never lose access to what you paid for.
The never-lose-access rule: every version released while your license is active is yours permanently. If you stop renewing, the app keeps working, you just stop getting new versions. No hostage software here.
Free means free for personal, non-commercial use, with every feature. The business tiers fund development. If home users spread the word, that trade works for everyone.
Using ShrinkRay for work that generates income: client documents, work files, business research. Using it for your kid's homework, personal projects or your own household paperwork is personal use. We built the honor system in, and business audits keep companies honest.
No. Conversion, OCR, everything runs locally on your PC. ShrinkRay makes no network connections. You can run it with Wi-Fi off and confirm for yourself.
Measured results: a Word report shrank 96% (9,400 to 346 tokens), an Excel workbook 93%, web pages typically 80–94%, text PDFs 33–70%. Scanned PDFs become usable text that AI chat tools could not read at all. The app shows exact before/after numbers on every file.
You keep everything you have. Any version released during your license period runs forever. Expired licenses only stop new updates.
Yes — free download above, same features as Windows. If your Mac says the app can't be opened, make sure you downloaded from this page or our GitHub releases.
