Every form I deal with asks for "a scanned copy, PDF, under 200 KB". Visa portals, university applications, the bank. Nobody I know owns a scanner anymore, so people photograph the page on a table and run it through some free converter site. Which means their passport or ID card now sits on a server they know nothing about. So I built LensUp. You pick a photo, it finds the page, straightens it, whitens the paper and gives you a PDF. All of it happens in the browser tab and the file never leaves your device. I tested it yesterday with a 2400x3100 test image of an invoice lying at an angle on a desk (457 KB). It straightened it automatically in about 2 seconds on my laptop, and the export was a one-page A4 PDF of 112 KB. I kept the network tab open the whole time and nothing big went out. It has limits. It only finds the corners on its own when the page edges stand out from the background, so with white paper on a white desk you drag the four corners yourself. Compressing to a size limit is best effort and sometimes lands a little above the target so the text stays readable. And the PDF it makes is an image, so you can't select the text in it. Free, no account, no watermark: https://lensup.ai The part I'm least sure about is trust. If you had to scan your ID, what would you need to see before you believed a site that says nothing gets uploaded?   submitted by   /u/Murky_Ad8671 [link]   [comments]
