Can I edit or delete the text that's already in the PDF?

No — this tool adds new text on top of existing pages; it doesn't modify what's there. Replacing existing text reliably would require reflowing the document, which isn't safely automatable for arbitrary PDFs. To obscure existing content, the Redact PDF tool removes it properly.

How do I figure out the right coordinates?

Estimate from the page size and iterate. Y counts up from the bottom: on Letter (792 pt tall), the top inch is Y ≈ 720–790, the middle is ~396, the bottom inch under 72. A signature line two-thirds down an A4 page sits near Y ≈ 280. One or two test runs gets you on target.

Is the added text selectable and searchable afterwards?

Yes. The text is drawn into the page's content stream as real text — it copies, searches, and prints exactly like the rest of the document.

Can I use other fonts or colors?

Additions render in black Helvetica, regular or bold, at your chosen size. That covers form-filling and annotation; decorative typography is out of scope for this tool.

The form I'm filling has real input fields. Should I use this?

Use the Fill PDF Forms tool instead — it detects interactive fields and fills them properly, no coordinates required. This tool is for flat pages with nothing interactive on them.

About Edit PDF (Add Text)

Full PDF editors are heavy, expensive, or both — and most everyday 'editing' is really one task: putting some text onto an existing page. A date on a form. A name on a line. A note in a margin. Convertora's edit tool does precisely that: you specify the text, the page, and the position, and it's drawn permanently into the document.

Placement works by coordinates rather than clicking on a preview: X is the distance in points from the left edge, Y the distance from the bottom (PDF's native convention). At 72 points per inch, an A4 page is 595 × 842 points and US Letter is 612 × 792 — so Y around 750–790 is the top of a Letter page, and the default position (50, 700) lands in the upper-left region. You can queue any number of text additions, review them as a list, and apply them all in one pass.

Each addition supports its own font size and an optional bold weight, rendered in black Helvetica. Once saved, the text is part of the page content — it prints, copies, and behaves like the document's original text.

How to use it

1Upload your PDF (up to 100 MB).
2For each piece of text: enter the text itself, the page number, the X and Y coordinates in points, the font size (default 12), and tick Bold if needed.
3Click Add Text to queue the addition. Repeat for as many additions as you need — they appear in a list where any can be removed.
4Click Save. All queued text is drawn into the document in one pass, and the result downloads with an -edited suffix.
5Off-target? Adjust the coordinates and run again from the original — iterating is quick since nothing is uploaded.

Common use cases

Filling in a flat (non-interactive) form — names, dates, and amounts at the right spots on the page.
Adding a date or reference number to a document before filing it.
Labelling figures or marking a revision note on specific pages.
Inserting 'COPY' or a routing note on the first page of a duplicate.

Frequently asked questions

Tips

Queue all your additions and save once — one output file beats five rounds of download-and-re-upload.
Writing on a printed line? Set Y a few points above the line itself, since coordinates position the text's baseline.

100% private — runs in your browser

Convertora processes everything on your device using JavaScript and WebAssembly. Files never leave your browser, are never uploaded to a server, and are never seen by us or anyone else. The moment you close the tab, the data is gone — there is no temporary cloud copy, no log entry, no retained backup.

Because the work happens locally, processing speed depends on your device — but there are no rate limits, no daily caps, and no file size restrictions beyond what your browser can handle in memory. No signup, no account, no payment. The tool works the same in incognito mode, on a corporate network, or after the page has loaded once, even with the network disconnected.
