What is a Escanear a PDF?
Turns your phone or webcam into a document scanner — useful for a paper receipt, a signed form, or a page from a book that needs to become a shareable PDF, without a dedicated scanner app or a trip to a physical scanner. A photo taken at an angle doesn't have to stay that way: drag a page's 4 corners onto its actual edges and it's warped flat, the same crop-and-straighten step a real scanner app walks you through.
How to use the Escanear a PDF
- Capture pages with your camera, or upload photos
- Straighten and enhance any page that needs it, then reorder as needed
- Download the assembled PDF
Example
Capturing 4 photos of a signed rental agreement's pages, straightening the one shot at an angle by dragging its corners onto the page's edges, then reordering page 3 and 4 after noticing they were swapped, produces one clean 4-page PDF once downloaded.
Why use Escanear a PDF
Straighten any page yourself
Drag 4 corner handles onto the document's actual edges in the photo, and it's warped into a flat rectangle.
Enhance a dim photo
A real auto-contrast pass brightens a washed-out or dim capture so the text actually reads clearly.
Camera or upload, in any order
Capture pages live, upload photos you already have, or mix both — then reorder before assembling.
What can you create?
Digitize a signed paper form
Photograph a signed lease, waiver, or form and turn it into a shareable PDF without a scanner.
Straighten a photo taken at an angle
Fix a page that wasn't shot square-on by dragging its corners onto the page's actual edges.
Scan a receipt for an expense report
Capture a paper receipt and get a clean, legible PDF page instead of a raw photo.
Frequently asked questions
Is my PDF uploaded anywhere?
No — Escanear a PDF runs entirely in your browser using JavaScript/WebAssembly. Your PDF is never sent to a server.
Is there a file size limit?
Free use covers files up to 100MB per file; signing up for Pro raises that to 500MB.
Does this automatically crop or straighten a photo taken at an angle?
Not automatically — there's no edge detection that finds the document for you. But you can straighten any page yourself: click "Straighten," drag the 4 corner handles onto the document's actual edges in the photo, and it's warped flat into a proper rectangle.
What does the "Enhance" option actually do?
It's a real auto-contrast pass, not a cosmetic filter — it finds the darkest and lightest tones actually present in the photo (ignoring the extreme 1% as outliers) and stretches that range to full black-to-white. A dim or washed-out photo gets genuinely brighter and more legible; it isn't guaranteed to help a photo that's already well-lit.
Can I mix live camera captures with photos I already have saved?
Yes — you can add pages both by capturing live and by uploading existing photos, then reorder them together into one final PDF.
