Pick a tool. Get it done.
Most ShellPDFs tools run entirely in your browser, so your files never leave your device. For tasks that genuinely need server resources, like PDF to Word, webpage capture, and higher-grade compression, we use isolated workers with short-lived storage and strict deletion rules. The goal is simple: clear tools, honest privacy boundaries, and helpful guidance around each workflow.
How much does compression help?
Scanned documents
40–80% smaller
Image-heavy PDFs
30–60% smaller
Text-only documents
5–20% smaller
Actual results depend on document content and compression level selected.
What makes ShellPDFs useful
Ad-supported utility sites often look interchangeable. ShellPDFs is built around a different promise: explain how each tool works, be clear about what stays on-device versus what uses a secure worker, and publish guides based on real product workflows instead of placeholder copy.
Browser-first by design
Merge, split, organize, rotate, remove pages, protect PDFs, and export data without uploading the source file.

When a workflow needs server-side processing, ShellPDFs uses isolated jobs, rate limits, and short-lived storage instead of turning your file into permanent content.

Best for sensitive files and fast repeat work
- Use these when you want zero-upload handling on the device you already trust.
- Ideal for page organization, document cleanup, Markdown export, and table extraction from searchable PDFs.
- Works especially well for teams that need a quick utility without opening a desktop app.
Secure cloud tools
Used only where browser limits would hurt the result
- ShellPDFs uses server-side jobs for webpage rendering, DOCX conversion, and stronger PDF compression — including when you need to compress pdf to 2mb for portals and forms.
- Those jobs are temporary by design, with deletion rules documented in the privacy and terms pages.
- You still get the same goal: fast completion, transparent limits, and no long-term file hosting.
