Image Tools
Resize, compress, convert, crop and clean up photos — including passport, ID and favicon presets.
Formats
Conversion Tools
Turn files into PDF, pull PDF apart into Word, text, JPG, PNG, WEBP or CSV, and convert between image formats.
Word, Excel and PowerPoint files open in the browser for reading, but faithful DOCX/XLSX/PPTX → PDF rendering needs a server-side LibreOffice engine. Those tools are labelled Coming soon rather than faked — see our honesty policy.
Security & privacy
Your files never leave your device
Most online converters upload your document to a server, keep it for an hour (or a week), and ask you to trust their deletion policy. ScanMaster has no upload step at all: the code that compresses, merges and converts runs as JavaScript inside your browser tab.
Zero uploads
No file ever leaves the browser — nothing to breach.
Encrypt & redact
Password-protect, permanently redact and strip metadata.
No account
No email, no cookie tracking of your documents, no profile.
Local signatures
Draw or upload your signature; it is baked in, not stored.
Why ScanMaster
Why Choose ScanMaster
Built for people who just need the job done — no funnel, no upsell, no waiting room.
Nothing is uploaded
Processing happens on your device. Files never touch a server, so there is no breach risk from us — because there is no us.
Free, no account
No signup wall, no trial, no watermark stamped onto your output. Open a tool and start working.
Instant results
No upload time, no queue, no download link in your email. Large files stay fast because the work is local.
One toolkit, 238+ tools
PDF organizing, conversion, compression, editing, signing, OCR, image resizing and metadata work in one place.
Works offline-ish
Once the page is loaded, the processing engine is already on your machine — flaky connection included.
Honest status labels
Where a feature needs server muscle, we say so on the page instead of pretending the file was converted.
FAQ
Frequently Asked Questions
Do my files get uploaded to a server?
No. Every tool runs entirely inside your browser using JavaScript and WebAssembly. Your PDFs, photos and documents never leave your device, which is why there are no queues, no daily limits and no account required.
Is ScanMaster really free?
Yes — all browser tools are free with no signup, no watermark added by us, and no file-count limit beyond a sensible 50-file / 100 MB per-batch safety cap.
What file formats are supported?
PDF plus JPG, JPEG, PNG, WEBP, AVIF, GIF, BMP, TIFF, SVG and HEIC/HEIF images, and text formats such as TXT, MD, HTML, CSV, JSON and RTF. Each tool page lists exactly what it accepts, and the formats page gives the full matrix.
Why do some tools say “Partial” or “Coming soon”?
A few operations — faithful Word/Excel/PowerPoint conversion, PDF linearization, ML background removal — need server-side engines such as LibreOffice or a GPU model. We label those honestly instead of quietly handing you back an unconverted file.
Can I use ScanMaster on a phone?
Yes. The whole site is responsive and camera capture (Scan to PDF) is built for phones. Because processing is local, large files stay fast on modern mobile browsers too.
Is it safe to process confidential documents?
For browser tools, yes: nothing is transmitted. Your browser's own memory holds the file, and closing the tab discards it. Sanitize, Redact and Remove Metadata tools exist specifically for pre-sharing cleanup.
Do you store my recent tools or settings?
Only in your browser's localStorage — theme choice, recently used tools and your My Space favourites. Nothing is sent anywhere and you can clear it at any time from My Space.
Why is my PDF to Word output plain text?
PDF has no concept of “paragraphs” or “reflow”; it stores positioned glyphs. We rebuild the reading order and give you DOCX, TXT, HTML, Markdown or RTF, but exact magazine-style layout needs a desktop conversion engine.
