You've done everything right. Uploaded the PDF. Waited for the tool to process it. Clicked "Download." And then a signup wall appears. Enter your email. Confirm it. Now you can have the file you already processed.
This has become the default pattern for most online PDF tools. The processing is technically free. The download requires your email address. It's a reasonable trade if you want ongoing access — but it's not what "free" implies when you first land on the page.
A few tools still skip that step. Here's which ones actually deliver, and what each handles well.
Why Most "Free" PDF Sites Now Ask for an Account
Smallpdf was one of the first major online PDF tools, and for years it let you upload, process, and download without creating anything. That changed when the company moved to a mandatory account model — even for the free tier. The upload still works without a login. The download doesn't. The free tier caps you at two tasks per day and the interface pushes you toward a paid plan. The tool itself hasn't changed; the account requirement is purely for lead generation.
ILovePDF takes a softer approach. Many tools work without an account, but guest users face tighter file size limits (100 MB vs 200 MB for registered users) and the interface persistently nudges toward signup at every step. It's not a hard wall, but it's engineered to erode resistance.
Adobe Acrobat Online (acrobat.adobe.com) sits at the far end of this spectrum. Basic operations — compress, merge, convert to Word — are available on the free tier, but Adobe requires an Adobe ID to download anything. Reasonable if you're already in the Adobe ecosystem. For a one-off task from someone with no Adobe products, it's a heavy requirement for a file you already own.
Understanding these tradeoffs before starting saves you from completing work and then discovering you can't have the output without an account.
PDF24 — The No-Signup Benchmark
When you need to merge two contracts before sending them off, or compress a scanned document that's ballooned to 25 MB, PDF24 Tools is where to start. No signup. No watermarks. No artificial daily limits.
The tool list covers what most people need: merge, split, compress, rotate, reorder pages, add page numbers, convert to and from Word and Excel and JPG, apply password protection, remove a password, and OCR a scanned document to make its text searchable. Twenty-four tools in all, every one of them usable without creating an account.
Two specifics worth knowing. First, compression options: most online compressors give you one output quality with no control. PDF24 offers "Recommended", "Strong", and "Extreme". On a 20 MB scanned invoice, "Recommended" typically brings it to 8–10 MB with no visible quality loss. "Strong" goes to 4–5 MB with slightly softer images — fine for anything read on screen rather than printed. Second, the privacy policy: PDF24 is operated by geek software GmbH in Germany, and their published privacy policy states uploaded files are deleted from servers within hours of processing. Most competitors are vaguer about this specific detail.
PDF24 is the tool I'd bookmark first. No account ever required, no watermark on output, and the compression quality control is a genuine advantage over the alternatives.
TinyWow for When You Have Mixed Tasks
TinyWow covers the same PDF operations as PDF24 — merge, split, compress, convert — plus video editing, image processing, and general file conversion. No account required for any of it.
For PDFs specifically, TinyWow includes an "Edit PDF" mode that lets you place text boxes, shapes, and images anywhere on the page. This matters for a common problem: scanned forms with printed blank lines where you need to type. The fields aren't interactive form fields — they're images of blanks — so standard form-filling tools skip right over them. TinyWow lets you position a text box precisely over each blank and type. Positioning takes a few minutes on a complex form, but it works cleanly.
TinyWow is ad-supported. Expect banner ads, not popups. The ads don't interrupt the workflow. If that bothers you, PDF24 is the ad-free alternative for PDF-only work. If you have a mixed queue — compress a PDF, resize an image, trim a short clip — TinyWow handles all of it in one place without requiring an account for any task.
Form Filling and Text Editing: Where Tools Differ
For PDFs with actual interactive form fields — the kind you click and type into — most of the tools above handle these without issue. The harder cases are flat PDFs: scanned documents, printed forms that were never designed as digital forms, any PDF where the blanks are visual rather than functional.
For those, Sejda is the most precise option. It opens PDFs in a browser-based editor and lets you click on existing text to edit it inline — not just overlay new text on top, but actually modify the words already there. Font substitution isn't always perfect if the original used custom embedded typefaces, but documents built with standard system fonts (Times New Roman, Arial, Helvetica) typically edit cleanly.
Sejda limits free users to three tasks per hour without an account. That's not much for heavy use, but for occasional editing it's usually sufficient. The counter resets on its own; no account needed to extend it.
One thing that applies to all of these tools: none of them save your work between sessions. Upload, fill, download — and the tool forgets everything. That's the privacy-friendly design at work. No session data retained, nothing stored between uses. The practical workaround for forms you fill repeatedly is saving a partially completed template locally and uploading it as your starting point each time.
OCR: The Step Most People Skip
Scanned PDFs are a special problem category. They look like PDFs but contain no actual text — just an image of text. You can't search them, select text from them, or edit their content. Optical character recognition (OCR) converts the image layer into real, searchable, selectable text.
PDF24's OCR tool handles this without an account. Upload the scanned PDF, run OCR, download a version where the text layer has been added. The visual appearance stays the same; what changes is the underlying data. Quality depends heavily on scan quality — a clean 300 DPI scan produces near-perfect OCR; a blurry phone photo of a document taken at an angle does not.
The order of operations matters: OCR first, then edit. If you try to select or edit text in a scanned PDF before running OCR, there's nothing to work with. Run OCR, confirm the text layer looks correct, then open the resulting PDF in Sejda if you need to change the actual content.
For large scanned batches — a multi-page report, a stack of archived invoices — PDF24's OCR processes each page in sequence. A 30-page document takes roughly 30 times as long as a single page. Worth knowing before committing a large file to an online tool on a slow connection.
What Each Tool Actually Requires
| Tool | Account Required | Limits | Ads | Watermarks |
|---|---|---|---|---|
| PDF24 | Never | None | None | None |
| TinyWow | Never | None | Banners | None |
| Sejda | Never | 3 tasks/hour | None | None |
| PDFescape | Never | 10 MB / 100 pages | Minimal | None |
| Smallpdf | Required to download | 2 tasks/day | Minimal | None |
| ILovePDF | Pushed but optional | Tighter for guests | Moderate | None |
| Adobe Acrobat Online | Required to download | Some tools limited | None | None |
The pattern is consistent: tools with legitimate business models based on subscriptions and upsells tend to use account requirements as a friction mechanism. Tools with ad-supported or freemium-without-gate models tend to skip that friction. PDF24 and TinyWow are both in the second category.
What Happens to Your File After You Upload It
Every online PDF tool processes your file on a server. Your document leaves your device, gets transformed, and comes back. For routine files — a conference schedule, a lease summary, a form you're submitting to a city agency — this risk is low. For anything with sensitive personal information, financial details, or confidential business content, check what the tool actually does with uploaded files before you use it.
PDF24 and Sejda both explicitly state that uploaded files are deleted within hours of processing. Smallpdf's policy states files are deleted within one hour for guest users. ILovePDF states two hours. Adobe Acrobat's retention terms for guest uploads are less clearly specified in their public documentation.
One warning that applies without exception to every tool in this list: drawing a black box over text doesn't actually redact it. That's true in online editors and in most desktop software too. A visual cover doesn't remove the underlying text from the PDF's data structure — anyone who extracts the raw text content of the file can still read what's "covered." Real redaction requires software that permanently removes content from the file's structure. For legal documents, medical records, or anything where the hidden information must actually stay hidden, none of these tools are appropriate for redaction.
For everything else — merging, compressing, filling in forms, editing a word in a contract, making a scanned document searchable — the no-login tools work. You get the result, close the tab, and leave nothing behind. No account in the tool's system. No email in a marketing list. No user profile built from your document processing history.
