PDF tools & API

PDFs, cut to fit.

Merge, split, stamp, fill and read PDFs. Free in your browser, where files never leave the device, or by API for your code and your agents.

Nothing uploaded
No sign-up
No watermark
No daily limit

The tools are free. The API is free for 150 documents a month, with plans from $9.

Do it here

Every tool runs in this tab on the same code as the API. Nothing is uploaded, nothing is kept, and there are no limits beyond your device.

Merge PDF options

Fields with the same name in two files are renamed (name_2), so filling one never fills the other.

The same thing with the API

Four verbs

One API for documents: send a file by id, URL, base64 or as the body, and every result comes back as a file whose id goes straight into the next call.

Make

HTML to PDF in a real browser, with {{variables}}, repeating invoice rows, page numbers in the footer and bookmarks from headings. Save it as a template and print it by id. Or a public URL, or images.

POST /v1/pdfs
POST /v1/templates

Change

Merge, split, reorder, rotate and delete pages; stamp text, images, QR codes, watermarks and page numbers.

POST /v1/merge
POST /v1/split
POST /v1/pages
POST /v1/stamp

Fill

Fill a PDF's own form fields by name, or place values on any PDF by position. Save it as a template; fill by id.

POST /v1/fill
POST /v1/templates

Read

Text per page, markdown for LLMs, form fields with their options, and the facts: pages, sizes, encryption.

POST /v1/extract

The API

JSON in, files out. Files go in as a fil_… id, a public URL, base64, the raw body, or multipart; results are hosted at a URL for 24 hours, or as long as you ask.

HTML to PDF with variables, headers and footers; merge, split, pages, stamp, fill, templates, protect, unlock, extract; images to PDF
Errors that name the field: password_required, files[1].pages
A fill never fails whole: values a field will not take come back with the reason
Every response says what is left of your plan (X-Gw-Remaining)

For agents

The same operations as MCP tools, so an agent can read a contract, fill a form or bundle a report without glue code. Files go to tools as URLs or ids, never as megabytes of base64 in the chat.

extract_pdf returns markdown for the model, and lists scanned pages it could not read
fill_pdf reports unknown and rejected fields instead of failing
Every tool marks itself read-only or not, so clients can approve sensibly

The details we fussed over

Deleted means deleted

Most PDF libraries hide a removed page and keep its contents in the file. pdfedge removes it from the bytes.

Forms survive

Merge two forms and every field still works. A name used twice becomes name_2, so filling one never fills the other.

Any script

Greek, Cyrillic, Polish, Japanese: text Helvetica cannot draw switches to Noto Sans, or to any Google Fonts family you name.

Placed as seen

Bottom-right is the bottom-right the reader sees, on rotated and cropped pages too.

Gone in a day

API files are deleted after 24 hours unless you ask to keep them. The tools here never upload at all.

One plain unit

A document is one operation on up to 50 pages. Uploads, reads and templates are free.
