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 the tiny PDF tools on TinyPDFTools have a specific answer for each one.
This is the complete map: all 16 free tools, organized by what they do, with a guide to matching your situation to the right tool. Merge PDF → is the most-reached-for tool on the site, but there are 15 more — each free, no signup required, and no watermark on output.
Key Takeaways
- TinyPDFTools has 16 free, browser-based PDF tools covering every common PDF task — merging, splitting, compressing, converting, editing, and signing.
- Gmail caps attachments at 25 MB; desktop Outlook at 20 MB (Google, Microsoft). The Compress PDF tool handles both limits in seconds.
- All tools run client-side — your files are never uploaded to a server, stored, or shared with any third party. No account is required for any feature.
All 16 Tiny PDF 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 usage than any other — but it's only one of the five task categories TinyPDFTools covers. Here's the full index.

Which Tool Do You Need? Five Real Scenarios
Not sure which tool fits your situation? Match your task to the right one below. These are the five 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, drag to reorder them, click Merge, download the combined file. It handles up to 50 files per session.
"My scanned PDF is 19 MB and Outlook won't send it." Use Compress PDF. Scanned documents — photos of paper pages — compress well because they contain large image objects that the compressor can reduce without visible quality loss. A 19 MB scan often becomes 3–5 MB. Click Upload, let it process, click Download.
"I need just page 12 from a 50-page report." Use Extract PDF Pages. Type the page number, click Extract, download the single-page file. This is faster than Split when you only need a few pages from a larger document.
"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 — they merge into a single, submission-ready PDF. Drag to reorder before downloading if the chronological order matters.
The Tool Combination Most Users Discover Too Late
Merge and Compress are both on the homepage because they work better in sequence than in isolation. Here's why.
When you merge several PDFs, the output is often larger than you expect. Each source file brings its own fonts, embedded images, and metadata — and those resources stack up in the combined file rather than deduplicating automatically.
Running the merged file through Compress PDF as a second step consolidates those shared resources. In practice, a merged document that clears 25 MB often compresses back below the Gmail limit (Google) and well under desktop Outlook's 20 MB cap (Microsoft).
The workflow: Merge PDF → download → drag that result into Compress PDF → download again. Two steps, about 60 seconds total.
Why Your Files Never Leave Your Device
Every tool on TinyPDFTools runs in your browser using JavaScript. When you click Compress or Merge, your browser processes the file locally — no file content is transmitted to any server.
TinyPDFTools processes all files using the PDF-lib JavaScript library. Your browser downloads the library when you load the page, then runs it locally on your file. Nothing is uploaded. Nothing is stored. There is no server-side record of your document.
This 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 conversion finishes. If you wouldn't email a document to a stranger, you should care where it goes during processing.
TinyPDFTools processes PDF files client-side using the PDF-lib JavaScript library, meaning your file never leaves your device during any operation. This is verifiable: 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 involves our servers.
Frequently Asked Questions
Is TinyPDFTools really free for all 16 tools?
Yes — there's no premium tier, no daily task limit, and no features locked behind a subscription. All 16 tools are fully functional at no cost. No account, no email address, and no payment information is ever required.
How large a file can I process?
Browser-based processing depends on your device's RAM, not a server cap. Most modern laptops handle files up to 500 MB without issues. Gmail's 25 MB attachment limit (Google) is the practical ceiling for most tasks — and Compress PDF can get most files under that threshold.
Does TinyPDFTools work on mobile?
Yes. All 16 tools work in current versions of 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. When you close the browser tab, the in-memory file data is released. Nothing is written to a server — because the processing never involves a server. Your file exists only in your browser's memory while you're actively working on it.
Can I use TinyPDFTools if my internet connection is slow or drops?
After the initial page load, most tools continue working if your connection drops — the JavaScript library is already loaded locally. You need a connection to load the page initially and to download your output file, but the conversion step itself runs offline.
Start Here
If this is your first visit, Merge PDF covers the most common starting task. Drag in your files, preview the order, download the result. If the combined file is larger than expected, run it through Compress PDF as a second step.
All 16 tools follow the same pattern: upload (or drag in), configure if needed, download. No account. No watermark. No upload to a server.
