Unlimited Sign PDF
Sign PDF without limits — no daily quota, no cap on the number of files, and no maximum size beyond what your own device can handle. Server-based tools ration free usage because every file costs them CPU and bandwidth. ContinuePDF processes your PDF on your machine, so there is no server capacity to ration and nothing to throttle.

What you can do with Sign PDF
Signing adds your actual signature to a PDF — drawn, typed, or uploaded as an image — and places it exactly where the document needs to be signed, so you can return it without printing.
Sign a contract fast
Add your signature to an agreement and send it back the same day, with no scanner or printer needed.
Handle forms remotely
Sign school, medical, or HR forms from home and email the signed copy straight back.
Initial every page
Place your initials on each page of a multi-page contract where that is required.
Reuse a saved signature
Sign recurring paperwork with a consistent, professional-looking signature every time.
Genuinely unlimited Sign PDF
Free online tools usually meter you: a few files a day, a small maximum size, or a cooldown between jobs. That is because each operation runs on their servers and costs them money, so they cap free users to control the bill and nudge you toward a paid plan.
ContinuePDF has no such meter. Because your browser does the sign work, our costs don't rise with your usage, so we don't need daily caps or throttling. The practical ceiling is your device's available memory — modern laptops and phones comfortably handle large files and long batches — not an artificial quota.

Device-limited only
The only ceiling is your own hardware, not a paid tier.
Pro tip
Draw your signature slowly on a trackpad or touchscreen for a cleaner line, or upload a photo of your ink signature on white paper for the most authentic look. Size it to match the signature line rather than dropping it in oversized.
Frequently asked questions
Is a signature added this way legally valid?
In many places an electronic signature is acceptable for everyday agreements, but requirements vary by country and document type. For high-stakes legal documents, check what your jurisdiction or the other party requires.
Can I place the signature exactly where I want it?
Yes. You position and resize the signature freely, so you can drop it precisely on the signature line and add a date next to it if needed.
How many files can I sign?
As many as you like. Sign PDF has no daily limit and no per-file quota. Because processing runs on your device, there is no server capacity to ration — the only practical limit is your device's memory.
Is there a file size limit?
There is no fixed size cap. Large files simply take a little longer and depend on your device's available memory. For very large documents we suggest closing other tabs to free up RAM.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Sign PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
