Merge, split, convert, compress and secure PDF and Office documents. Every tool is free, works without an account, and processes your files in memory — never stored.
Everything you do with PDFs, in one place
The PDF is the paper of the internet — contracts, statements, forms, reports and scans all travel as PDFs because they look identical on every device and in every printer. The price of that reliability is that PDFs resist casual editing: you need a tool to combine them, pull pages out, shrink one for an upload limit, or turn it back into an editable Word document. This page collects all of those jobs in one place.
slimdocs runs the heavy document work on a secure server that holds your file in memory only for the seconds it takes to process, then drops it the instant your download begins. Nothing is written to disk and nothing is retained. Just as importantly, pages are never flattened into images: real text stays real text, so the documents you get back remain searchable, selectable and readable by screen readers.
If you are not sure which tool you need, start with the compressor. It accepts PDFs, images and Office files alike, tells you exactly how much smaller the result is, and refuses to hand back a file that came out larger than the one you gave it.
Frequently asked questions
Are these tools really free?
Yes — every PDF and document tool is free, with no account, no watermark and no daily limit. The site is supported by unobtrusive advertising, which is what keeps the whole toolkit open to everyone.
Where are my documents processed?
On a secure server that keeps your file in memory only for the few seconds the job takes, then deletes both the original and the result the moment your download starts. No copy is ever written to disk.
Will my text stay selectable?
Yes. Pages are never rasterized into images. Text stays real, searchable and accessible in every output — which is the main thing that separates slimdocs from cheap compressors that flatten everything.
Is there a file size limit?
There is a per-file cap to keep the service responsive for everyone; the tool shows the current limit on its dropzone. Everyday documents sit well within it.
Do you support password-protected files?
Yes, in both directions. Protect PDF adds password encryption to a document, and Unlock PDF removes a password you already know. slimdocs cannot and will not break a password you do not have.
