Typed "tinypdf" into Google and landed here? You're in the right place. TinyPDFTools (some people search it as one word, some as "tiny pdf," some as "tiny pdf tools" — same site either way) is a free, browser-based PDF toolkit. No install, no account, nothing uploaded to a server.
You need to combine five scanned documents before a 3 p.m. deadline. Or your PDF is 22 MB and Gmail won't let it through. Or a client sent you a form with the signature field in the wrong place. Each of those is a different task — and TinyPDFTools has a specific tool for each one.
This is the complete map: all 17 free tools, organized by what they do, plus a guide to matching your situation to the right one. Merge PDF → is the most-reached-for tool on the site, but there are 16 more — each free, no signup required, and nothing added to your file unless you ask for it.
Key Takeaways
- TinyPDFTools has 17 free, browser-based PDF tools covering merging, splitting, compressing, converting, editing, security, and signing.
- Gmail caps attachments at 25 MB; desktop Outlook at 20 MB (Google, Microsoft). Compress PDF handles both limits in seconds.
- All 17 tools run client-side — your files are never uploaded to a server, stored, or shared. No account needed for any feature.
All 17 TinyPDF Tools, Organized by Task
Gmail limits attachments to 25 MB and desktop Outlook to 20 MB (Google, Microsoft). That single constraint drives more PDF-tool searches than anything else — but it's only one of six task categories TinyPDFTools covers. Here's the full index, updated to include every tool currently live on the site.

Which Tool Do You Need? Six Real Scenarios
Not sure which tool fits your situation? Match your task to the one below. These are the most common cases we see — and they don't always map to the most obvious tool.
"I need to email several documents as one file." Use Merge PDF. Drag all your files in, reorder them if needed, click Merge, download the combined file. There's no fixed file-count cap — it's your device's memory that decides, not the tool.
"My scanned PDF is 19 MB and Outlook won't send it." Use Compress PDF. Scanned documents compress well because they're mostly large image data, and that's exactly what the compressor targets. In our testing, a scan in that size range typically drops to a few megabytes. Click Upload, let it process, click Download.
"I need just page 12 from a 50-page report." Use Extract PDF Pages, not Split. Type the page number, click Extract, download the single-page file — faster than splitting a whole document when you only need a slice of it.
"My scanner saved the whole batch sideways — all 18 pages." Use Rotate PDF. Click Select All, choose 90° clockwise, click Rotate. Download the corrected file.
"I have 15 receipt photos from a business trip to submit for reimbursement." Use Image to PDF. Upload all 15 images at once and they merge into a single, submission-ready PDF. Drag to reorder before downloading if chronological order matters.
"I'm sending a contract draft and don't want it mistaken for the final version." Use Watermark PDF before you hit send. Stamp "DRAFT" across every page, download, attach. Takes about 15 seconds and it's the single easiest way to stop a half-finished document from being treated as signed.
The Tool Combination Most Users Discover Too Late
Merge and Compress sit next to each other on the homepage on purpose. They work better as a pair than either does alone.
When you merge several PDFs, the output is often bigger than you'd expect. Each source file drags in its own fonts, embedded images, and metadata — and none of that deduplicates automatically just because the pages now live in one document.
Running the merged file back through Compress PDF cleans that up. A merged document that clears 25 MB will often compress back below the Gmail limit (Google) and comfortably under desktop Outlook's 20 MB cap (Microsoft).
The workflow: Merge PDF → download → drag that result into Compress PDF → download again. Two steps, about a minute, and it's the fix most people don't find until they've already hit "reply all" with a bounced email.
"TinyPDF" and "TinyPDFTools" — Same Site?
If you searched "tinypdf" specifically, worth clearing this up: there are other, unrelated desktop PDF utilities that use similar names, including older Windows print-driver tools. TinyPDFTools is not one of those. It's a website — tinypdftools.com — with no download, no installer, no separate desktop app. You open a tool in your browser tab and it runs immediately.
TinyPDFTools is a browser-based PDF toolkit, not a downloadable program. All 17 tools load from the website and process files locally using the PDF-lib JavaScript library — there is no installer, no desktop client, and no file upload step involved in any tool on the site.
If a search result took you somewhere else entirely, that's a different product. This guide only covers the tools at tinypdftools.com.
Why Your Files Never Leave Your Device
Every tool on TinyPDFTools runs in your browser using JavaScript and WebAssembly — a browser-native execution format that runs compiled code at near-native speed without leaving the page (MDN Web Docs). When you click Compress or Merge, your browser processes the file locally — nothing is transmitted to a server.
TinyPDFTools processes files using the PDF-lib JavaScript library. Your browser downloads the library once, when the page loads, then runs it locally against your file. Nothing is uploaded. Nothing is stored. There's no server-side record of your document.
That matters for tax returns, medical records, pay stubs, mortgage packets, and signed contracts. Most free PDF tools upload your file to a remote server to process it — and keep it there after the job finishes. The IBM Cost of a Data Breach Report 2025 puts the average breach at $4.44 million — a risk that only exists because files leave devices in the first place. If you wouldn't email a document to a stranger, it's worth caring where it goes during processing, too.
You can check this yourself: open browser DevTools (press F12), click the Network tab, then run any tool. You'll see requests for JavaScript and page assets — but no upload request carrying your file content. The processing never touches our servers, because there's nothing to touch.
Frequently Asked Questions
Is TinyPDFTools really free for all 17 tools?
Yes — no premium tier, no daily task limit, nothing locked behind a subscription. All 17 tools are fully functional at no cost, and no account, email address, or payment method is ever required.
How large a file can I process?
Browser-based processing depends on your device's RAM, not a server cap. In our testing, most modern laptops handle files well into the hundreds of megabytes without trouble — treat that as a rough guideline from typical use, not a hard spec. Gmail's 25 MB attachment limit (Google) is the practical ceiling for most email tasks, and Compress PDF gets most files under that in one pass.
Does TinyPDFTools work on mobile?
Yes. All 17 tools work in current Safari, Chrome, and Firefox on iOS and Android. Touch drag-and-drop works for reordering pages in Organize PDF and Merge PDF.
Are my files stored anywhere after I close the tab?
No. Close the tab and the in-memory file data is gone. Nothing was written to a server in the first place, because the processing never involved one — your file only ever existed in your browser's memory while you were working on it.
Is there a "tinypdf" download or app I'm missing?
No — and if a result promises one, it's probably a different product. TinyPDFTools is entirely browser-based. There's no installer, no browser extension, and no mobile app to download. Bookmark the homepage if you use it often; that's the only "setup" there is.
Can I use TinyPDFTools if my connection is slow or drops?
After the initial page load, most tools keep working even if your connection drops — the JavaScript library is already loaded locally. You need a connection to load the page and to save your output file, but the conversion itself runs offline.
Start Here
First visit? Merge PDF covers the most common starting task. Drag in your files, preview the order, download the result. If the combined file comes out bigger than expected, run it through Compress PDF as a second step.
All 17 TinyPDF tools follow the same pattern: drop your file in, configure if needed, download. No account. Nothing added to your file unless you ask for it. No upload to a server, ever.
