Merge & organize
Combine PDFs and images into one file, or tidy up a single PDF: reorder, rotate, delete, pull out just the pages you need, or print two or four pages on one side of a sheet.
Add more PDFs or images above to merge them. Click a page to select it. Drag to reorder — dragging a selected page moves all selected pages — or focus a page and press Shift + ← / →. With several PDFs, “Stack” shows a file as one card that moves as a whole.
Each sheet holds the next pages in the grid's order, scaled to fit. Portrait or landscape is picked to make them as large as possible. Use it for an ID card's front and back on one side, or to print two pages per side.
Add text & images
Click on the page where you want to place something, then press “Add to page”. Add your own text or image, or a ready-made tick, cross, box or arrow.
Standard fonts support Latin characters only.
72 points = 1 inch. The image's top-left corner goes where you click.
The middle of the stamp goes where you click — handy for ticking boxes on a form.
Watermark
Stamp text across the pages of a PDF.
Fill a form
Load a PDF with fillable fields, type in the values, and save.
Images to PDF
Turn photos or scans (JPG, PNG, HEIC, WebP…) into a PDF, one image per page.
Drag images to change the order — or focus one and press Shift + ← / →. Each image becomes one page, left to right, top to bottom. Click an image to view it full size.
Remove password
Unlock a password-protected PDF, or remove restrictions on printing, copying and editing, so it opens freely everywhere.
Only unlock PDFs you own or have permission to open. Your file and password never leave your device.
Lock PDF
Protect a PDF with a password, and optionally stop others printing, copying or editing it. Uses AES-256, the strongest PDF encryption.
Permissions password (optional)
Only needed if you want to lift the restrictions later in a PDF editor. If you leave it empty, a strong random one is used.
· Keep your password safe — a forgotten password can’t be recovered. Nothing is uploaded.
Crop pages
Trim the margins or keep just one part of a page. Set a crop area on each page, or use the same one for every page.
Drag across the page to choose what to keep. Drag the box to move it, or its handles to resize it.
Cropping hides what is outside the box; it stays in the file. To remove something for good, use Redact PDF.
Redact PDF
Black out names, numbers, signatures or anything else — for good. Drag boxes over what to hide, or find text to mark it everywhere.
Drag across the page to mark an area. Click a box’s × to remove it.
Finds every match on every page (not case-sensitive).
Pages with boxes are turned into images, so the hidden text is really gone — not just covered. Their other text can’t be selected afterwards. Pages without boxes stay as they are. Bookmarks, form fields and document info are removed.
Compress PDF
Make a PDF smaller to email or upload. The biggest savings come from photos and scans — text-only PDFs are usually compact already.
HEIC to JPG
Turn iPhone photos (HEIC / HEIF) into JPG, PNG or WebP files that open everywhere.
Photos keep their full size and are turned the right way up. Location and camera data (EXIF) are removed. Live Photos become still images. Other images (JPG, PNG, WebP…) can be converted too.
Compress images
Shrink photos and pictures from iPhone, Android or the web — HEIC, HEIF, JPEG, PNG, WebP, AVIF, GIF and BMP.
Location and camera data (EXIF) are removed. Animated GIFs become still images. Browsers can’t save HEIC, so iPhone photos are saved as JPEG unless you pick another format.
Resize photo
Set an exact size in pixels, mm, cm or inches — or pick a passport, visa or social media size and position the crop.
Drag the box to choose what’s kept. For passport photos, line the face up with the dashed oval.
Title & info
Change a PDF’s title — the name shown in the browser tab and reader’s title bar — and its other properties.
