PDF toolkit
Edit, merge, compress, convert and sign PDFs without installing anything. Leafstack runs most tools on your own device, turns scans into searchable text, and gets a contract countersigned before lunch.

Why it works
01 Merge
Drag the cover letter, the signed contract and the scanned receipts into one window. Reorder by thumbnail, drop the blank pages, and download a single file with a page count you can trust.
02 E-sign
Place signature, initial and date fields, add signers in order, and send. Each person signs in a browser on any device. When the last signature lands, the PDF is stamped and sealed with an audit certificate.
03 Compress
Pick a target such as email (under 10 MB) or upload portal (under 5 MB). Leafstack recompresses photos page by page and leaves text and vector drawings untouched, so the fine print stays fine.
Features
Six tools cover most of what people open a PDF app for. The other twelve are there when you need them.
Fix a typo, change a date or swap a logo right on the page. Fonts are matched automatically, so the edit doesn't look pasted on.
Drop in files, drag thumbnails into order, delete the blank page the scanner always adds. Bookmarks and links survive the merge.
Pick a target like "under 10 MB for email" and we choose image quality page by page. Text and vector drawings stay sharp.
Turn phone photos and old scans into searchable, copyable text in 9 languages. Crooked pages are straightened automatically.
Send for signature, set signing order, and get a certificate with timestamps and IP addresses attached to the final PDF.
Word, Excel, PowerPoint, JPG and HTML to PDF and back. Tables come out as real spreadsheet cells, not pictures of cells.
How it works
No account needed for your first three tasks a day.
PDFs, scans, phone photos or Office documents, up to 200 MB each. Drag them from your desktop or a synced folder.
Merge, compress, OCR, sign, redact or convert. Set a target size or page range, or keep the sensible defaults.
Get the finished PDF in seconds, share a link that expires in 7 days, or send it straight out for signature.
Testimonials
Sample reviews written for this template. Replace them with your own.
“Our weekly site survey is 60 pages of photos. It went from 41 MB to 6 MB and the client portal finally accepts it.”
“We send offer letters for countersignature through Leafstack. Median time from sent to signed is now under two hours.”
“OCR on scanned case files from the nineties, in Spanish, with the accents intact. I did not expect that from a browser tab.”
“Assembling the monthly board pack used to take twenty minutes in a desktop app. It takes two now, bookmarks included.”
“IT approved it in a week because most tools run locally. That conversation usually takes a quarter.”
“I fill out the same vendor forms a dozen times a year. With saved fields each one takes about 30 seconds.”

FAQ

Merge, split, rotate, compress, edit, redact and most conversions run on your device with WebAssembly, so the file never leaves your browser. OCR, e-sign and Office-to-PDF conversion run on our servers in Frankfurt; those files are encrypted in transit and deleted automatically after one hour.
It handles crooked, low-light phone photos and 200 dpi office scans well, in nine languages including German, Spanish, French and Japanese. Handwriting isn't recognized. You get the same-looking page with an invisible text layer, so it becomes searchable and copyable.
Signatures made with Leafstack are standard electronic signatures under ESIGN and UETA in the US and simple electronic signatures under eIDAS in the EU. Every signed file includes an audit certificate with signer emails, timestamps and IP addresses. Documents that need notarization are out of scope.
Free handles files up to 50 MB and three tasks a day. Pro raises that to 200 MB with unlimited tasks, and Team to 500 MB. A single file can have up to 2,000 pages, and you can merge up to 50 files at once.
It works in any current browser on Mac, Windows, Linux, iPad and Android. Once the page has loaded, the on-device tools keep working without a connection, which is handy on a train. OCR and e-sign need to be online.
Upload your existing fillable forms and they keep their fields. Team admins can import saved signatures and stamps, and on the Team plan we'll migrate up to 200 templates for you at no charge.
Cancel from the billing page in two clicks and keep Pro until the end of the period you paid for. If you upgrade and it isn't what you needed, email us within 30 days for a full refund — no exit survey.
Open a tab, drop the file, get on with your day. No account needed to try it.
