Sign a contract
Basic
▼
Scenario
You receive a contract by email as a PDF. You need to sign it and send it back without printing.
Select ✍ Sign from the Edit menu.

Click ✍ Download Signed PDF.
Advanced options
Image signature
Switch to 🖼 Image mode to upload a PNG of your existing signature (transparent background recommended). You can also paste it from clipboard.
Signature size
Under Advanced options, adjust Sig Width (pt) to make the signature larger or smaller on the PDF page.
Opacity
Reduce opacity for a more subtle, ink-like look.
Name & Date
Type your name and date in the text fields — they are placed alongside the drawn signature on each placement.
Mark a document as CONFIDENTIAL
Basic
▼
Scenario
You need to share a sensitive report with a partner but want every page clearly marked "CONFIDENTIAL" so it cannot be mistaken for a public document.
Select 💧 Watermark from the Edit menu.
Drop your PDF.
Type CONFIDENTIAL in the Watermark Text field.
Choose your preferred position: Center for a large diagonal stamp, or Tiled to repeat it across the whole page.
Click 💧 Apply Watermark & Download.
Advanced options
Font Size
Larger values produce a bigger stamp. 60pt is a good default for most pages.
Rotation °
Angle of the text. -45° gives the classic diagonal stamp look. Use 0° for a flat horizontal mark.
Opacity
Lower values make the watermark more transparent so the page content remains easy to read. 30–40% is typical.
Color
Red is common for CONFIDENTIAL/DRAFT; grey is more discreet.
Position
Top Left, Top Right, Center, or Tiled (repeats across entire page).
Turn phone photos into a PDF
Basic
▼
Scenario
You photographed 5 pages of a paper document with your phone. You need to send it as a single PDF to your accountant.
Select 📷 Scan from the Edit menu.
Drop your photos, or tap to open your camera roll and select multiple images at once.
Each image appears as a card. Drag the cards to reorder them into the correct page sequence.
Click the ✂ icon on any image card to open the crop & contrast editor for that photo.
Choose the Page Size (A4 is standard) and a margin if desired.
Click 🖼 Convert & Download.
Advanced options
Contrast slider
In the crop editor, increase contrast to make text sharper and background whiter — very useful for photos taken in poor lighting.
Crop tool
Draw a rectangle to keep only the document area and cut out the table, hands, or background around it.
Fit to image
Page size option "Fit to image" creates a page exactly the size of your photo — useful for photos that are not A4 proportions.
Protect a sensitive file before emailing it
Basic
▼
Scenario
You need to email a medical report to your doctor. The file contains highly personal information and you want to make sure only your doctor can open it.
Select 🔒 Encrypt File from the Security menu. Make sure Encrypt mode is selected.
Drop your file. Any format works — PDF, Word, Excel, images, anything.
Type a strong password. The strength meter shows how secure it is. Aim for "Strong" or "Very strong".
Click 🔒 Encrypt & Download. You get a file ending in .encrypted. Send that file by email.
Tell your doctor the password separately — by phone, for example. Never send password and encrypted file in the same email.
⚠ The password is never stored anywhere. If you lose it, the file cannot be recovered. Write it down somewhere safe.
Decrypt a file you received
Basic
▼
Select 🔒 Encrypt File from the Security menu, then click the Decrypt tab.
Drop the .encrypted file.
Enter the password that was used to encrypt it.
Click 🔓 Decrypt & Download. The original file is restored.
Redact names before sharing a document
Basic
▼
Scenario
You have a patient report that appears 30 times throughout the document. You need to replace the patient's name with "PATIENT" before sharing with a research team.
Select 🔍 Anonymize from the Security menu.
Drop your PDF. Page thumbnails load.
In the Keywords section, type the name to find (e.g. "John Smith") in the first field, and the replacement text (e.g. "PATIENT") in the second field.
Click + Add Keyword to add more pairs — email addresses, ID numbers, addresses, etc.
Click 🔍 Anonymize & Download. Pages where replacements were made are highlighted in the preview.
⚠ This tool works on the text layer of a PDF. Scanned PDFs (images) need OCR first to have a text layer that can be searched.
Make a PDF small enough to email
Basic
▼
Scenario
Your scanned invoice is 18 MB. Your client's email server rejects attachments over 10 MB. You need to shrink it.
Select ◉ Compress from the Process menu.
Drop your PDF. The original file size is shown.
Choose a compression level:
Light
Removes metadata and cleans internal structure only. File quality is 100% unchanged. Typical saving: 5–15%. Use this if the document has no images.
Aggressive
Re-encodes all images as JPEG at lower quality, strips fonts and annotations. Typical saving: 50–80%. Text remains selectable. Use for scanned documents.
For Aggressive mode, adjust the Image JPEG Quality slider. 25–35% gives the best size reduction while remaining readable. Below 20% may look blurry.
Click ◉ Compress & Download. The new size and reduction % are shown.
Make a scanned document searchable
Basic
▼
Scenario
You have a PDF that is just a photo of a document — you cannot click on any text, cannot search for words inside it, and cannot copy anything. You want to fix that.
Select 🔤 OCR from the Process menu.
Drop your PDF or image. The page count and file size are shown.
Select the Language of the text in the document. Matching the language improves accuracy significantly.
Optionally enter a Page Range (e.g. "1" to "5") if you only need to process certain pages — useful for very large documents.
Click 🔤 Run OCR & Download. A progress bar shows each page being processed. On slow computers this takes a few seconds per page.
The downloaded PDF looks identical but now has an invisible text layer — you can search, select, and copy text.
How it works: OCR processes one page at a time and releases memory after each page. This means even a 200-page document can be processed safely on any computer without running out of memory. You can click Stop at any time to get a partial result.
Advanced options
Language
Choose from English, French, Spanish, German, and more. Using the correct language improves word accuracy. For multilingual documents, use "English" as a default.
Page Range
Enter a start and end page to process only part of the document. Leave blank to process all pages.
Stop button
Pressing ⏹ Stop mid-process stops the OCR and gives you whatever pages have been processed so far.
