Frequently Asked Questions

Upload your PDF directly into the editor and use the toolbar — Add Text, Highlighter, Pen, Sign, and more — to make your changes, then click Download. The whole thing runs entirely inside your browser tab: there's no account to create, no credit card to enter, and no watermark stamped on your finished file.

The best free PDF editor is one that's actually free at every step — not just free to open, with a surprise paywall the moment you click Download. This app never asks for payment, a trial signup, or an account: every tool is unlocked from the first upload, and your file is processed locally on your own device rather than pushed through a server you have to trust.

Yes — this is a web app that runs directly in your browser tab, so there's nothing to download or install. Open the page, upload your PDF, and start editing immediately; your document never leaves your device, so there's no separate desktop program quietly syncing your files anywhere either.

Many PDF editors put their real editing features behind a recurring monthly subscription. This editor gives you the same core edits — adding text, signing, merging, rotating, removing pages — for free, with no subscription, ever, since every edit happens locally in your browser rather than on someone else's servers.

Yes. There's no sign-up form, no email address requested, and no login screen standing between you and your document.

Select a PDF to edit → — you can be editing within seconds of landing on the page.

This editor has no trial period, no feature gate that unlocks only after payment, and no hidden fee that appears at download. Every tool — Highlighter, Blackout, Sign, Merge, and the rest — is free the first time you use it and every time after, because nothing here is a paid product with a free preview; it's simply free.

You never need to enter a credit card — not to try it, and not to download your finished file. There's no payment form anywhere in this app, since nothing about using it is ever a paid action.

Yes — use the Convert to PDF button on the home page, or go straight to the JPG to PDF or PNG to PDF page, choose your image, and it becomes a real PDF in seconds. It's free, with no account, and once it's converted you can keep editing it like any other PDF — sign it, merge it with other pages, whatever you need.

Convert an image to PDF →

Yes — use the Convert to PDF button on the home page, or go straight to the Word to PDF page, choose your .docx file, and it's laid out into a real, text-searchable PDF — not a flattened screenshot of the page. Formatting carries over closely (paragraphs, headings, lists, basic tables, images) though not pixel-for-pixel; exact margins, multi-column layouts, and headers/footers aren't reproduced.

Convert a Word doc to PDF →

Yes, for the modern .pptx format — use the Convert to PDF button on the home page, or go straight to the PowerPoint to PDF page, choose your .pptx file, and each slide is laid out into one real, text-searchable PDF page. Each slide's real text and images carry over at their real position, though not pixel-for-pixel; exact theme colors, grouped shapes, tables, charts, and SmartArt graphics aren't reproduced. The older, pre-2007 .ppt format isn't supported — re-save it as .pptx first (using your presentation software).

Convert a PowerPoint to PDF →

Yes — the WEBP to PDF and HEIC to PDF pages handle both. HEIC is the format many phones save photos as by default, which plenty of sites and older software can't open at all; converting it here turns that photo into a PDF basically anything can open, with no app to install and nothing uploaded to a server.

Convert a photo to PDF →

Yes — the Scan to PDF page lets you take a photo of each page in turn with your phone or tablet's camera, right in the browser, with no app to install. Review, retake, or remove any page before combining them all into one PDF.

Scan a document to PDF →

Yes — each has its own dedicated page (TXT to PDF, HTML to PDF, Markdown to PDF, CSV to PDF). Every one produces a real, text-searchable PDF: a .txt file's line breaks are preserved exactly, HTML and Markdown keep headings/lists/tables/bold formatting, and a .csv file becomes a real bordered table (with quoted fields and embedded commas handled correctly, not a naive comma split).

Yes — turn on Viewing Mode (the eye icon, next to the dark mode toggle) for a clean, uncluttered way to go through a document. Tools like Highlighter and Pen are always just a tap away whenever you want to mark something up, and once you've picked one it stays ready to use, so you don't have to reselect it for every single highlight.

Try Viewing Mode →

Yes — upload your tax form and use Add Text to fill in blanks exactly where you need to, or Text Edit to correct text that's already printed on the form. Since tax documents are about as sensitive as paperwork gets, it's worth noting again: this one is processed entirely in your browser, never uploaded anywhere, which matters a lot more for a W-9 or 1040 than it does for a flyer.

Add text to your form →

Use Add Text for any blanks the contract needs filled in, then the Sign tool to draw or type your signature and drop it onto the signature line — all without uploading the contract to a server or creating an account just to finish a document you probably needed to send back today.

Sign a PDF →

Yes — the Sign tool lets you draw a signature with your mouse, trackpad, or touchscreen, or type it in a cursive font, save it for the rest of the session, and place it — or your initials, the same way — on as many pages as you need, all for free.

Add your signature →

Use the Blackout tool to drag a solid black rectangle over any text you want gone before sharing the file — an SSN, an account number, anything else that shouldn't be recoverable. This is real redaction, not just a visual cover: the page it's on gets flattened into a plain image at download, so the covered content is genuinely removed from the file, not just painted over. One honest tradeoff: that whole page loses its searchable/selectable text, not just the blacked-out part — every other page in the document is unaffected.

Black out sensitive info →

A flattened or scanned form usually has no fillable fields at all — just blank lines on an image. Use Add Text, click directly on each blank, and type; you can match the font size to the form and position it precisely, so it reads as a normally filled-out form rather than something scribbled over it.

Add text to a flattened form →

Yes — the experimental Fill Form tool scans the page for fillable spots (real interactive form fields when the PDF has them, or a best-effort visual guess at blank lines when it doesn't), highlights each one in orange, and walks you through them one at a time: type or sign, click Next Field, repeat. It's labeled experimental because detection quality varies — reliable on real, official fillable PDFs, and a best-effort guess on scanned or flattened ones, which can occasionally miss a blank or flag the wrong line. Either way, nothing is ever uploaded to a server to do this.

Try Fill Form →

Yes, all three: the Pen tool for freehand drawing or annotations in any color, Highlighter for marking up existing text in a translucent color, and Add Text for typed notes anywhere on the page.

Try it: Pen · Highlighter · Add Text

Yes — the Sticky Note tool drops a real, clickable PDF comment annotation anywhere you click, not just a flattened picture of one. Open the downloaded file in any standard PDF viewer and the note is still there, clickable and editable, exactly like a comment made in that app.

Try it: Sticky Note

Yes — drag over any line with the Strikethrough tool to draw a line through it, in black, red, blue, or green. Select it afterward to change the color, move it, resize it, or delete it.

Try it: Strikethrough

Yes — the Add Image tool lets you upload a JPG, PNG, or WEBP and click anywhere on the page to place it, then drag to reposition or resize it before downloading.

Try it: Add Image

Yes — the Edit Image tool detects images already on the page; click one to move it, resize it, or delete it, right in your browser.

Try it: Edit Image

Use the Watermark tool and type your text — it's stamped, centered, on every page in one action, in a pale gray that doesn't obscure the content underneath.

Add a watermark →

Use the Page Numbers tool — pick a format ("1", "Page 1", "1 of 12") and a corner, and every page gets numbered automatically in one action.

Add page numbers →

Use this editor — it never stamps a watermark on your download, at any point, on any plan, because there is no plan. What you see in the editor is exactly what downloads.

Click Download. That's the entire fee: none. There's no paywall between finishing your edit and getting your file — that's true of every tool in this app, not just the free ones.

It's a common pattern: the editing experience is free to try, but the actual download — the one thing you actually need — sits behind a paywall, a watermark-removal fee, or a forced trial signup. This app doesn't do that anywhere; downloading your finished PDF is part of "free," not a separate, paid step.

Every edit — adding text, signatures, highlights — layers on top of your PDF's existing content without re-processing or re-rendering the rest of the page, so your original formatting, fonts, and images stay exactly as they were unless you specifically choose to compress on download.

Use Text Edit to replace existing text — it automatically detects and matches the original line's font, size, and color, so a correction blends in rather than looking pasted on top. For brand-new text, Add Text gives you a real font picker, including serif, sans-serif, and monospace options, so you can match the document's existing style.
