Is the PDF from the scanner more than one page?

The scanner builds one A4 portrait PDF and embeds the capture as a JPEG at quality 0.92. Scan each sheet on its own, then merge those PDFs if the portal wants a packet. A set at or under 100 MB can join in the browser.

When should I download the PNG instead?

When the form wants an image, not a page. The PNG is the scan itself. Use the PDF when you are about to merge receipts or attach a sheet that should print like paper. Neither download repairs a photo that missed a corner.

What does Magic Color change?

It boosts contrast and color so gray paper reads more clearly. It does not recover faded thermal ink or remove a shadow that covers the total. Fix the light and the curl first, then try the filter and compare the total at full zoom.

Can I search the scanned receipt for the total?

Not from the scan alone. The PNG and the one-page PDF are pictures. Searchable text is OCR, which is a Pro or Ultra step after you have a sharp capture. Highlight-testing a born-digital PDF is a different job.

How do I keep a stack of receipts in order?

Name each download as you go, in the order you will file them, then merge. Drag the PDFs into reading order. If mail rejects the size, compress the merged packet once and read a middle receipt before you delete the singles.

Scan receipts: edges and order

Q: Does the scan stay on the server?

The capture runs in the browser. If a later conversion uploads, those files are deleted after processing, typically within one hour and no later than 24 hours. Keep your own copy. The paper stays until the expense is actually paid.

Document Scanner Tips for Receipts, Contracts, and Homework

A document scanner in the browser is a perspective and contrast tool, not a magic copier. Convertify4u’s /document-scanner helps you turn a phone frame into a flattened page. The paper still has to be lit, flat, and fully in view. If the thermal receipt is curled into a tube under a restaurant lamp, no crop will invent missing ink.

Lighting before you tap capture

Stand so your shadow is not the main character. Avoid a window blasting through thin paper (you will read the reverse side). Thermal receipts fade; scan the same day when you can. For homework, take the sheet off a glossy desk — reflections kill both human reading and later OCR.

Fill the frame with the page, then leave a slim margin so corners are visible. The flattener needs corners. A crop that already chopped the signature line cannot be recovered in software.

Convertify4u scan flow

Open /document-scanner on a phone if that is your camera, or upload an existing capture from Files.
Instant-labeled scanning stays on-device when the product says Instant. Cloud is for jobs that need a worker; those uploads are HTTPS and auto-delete.
Capture or drop the image. Confirm the detected edges match the real page, not the table grain.
Export PDF for packets, JPG for a single image field on a form.
For multi-page expense reports, scan each receipt, then /convert/merge-pdf in date order.
If you need searchable text (Ctrl+F on a contract), that is OCR — Pro ($9.99/mo) on Convertify4u, not a free digital convert pretending to read pixels.
Keep paper until reimbursement clears. Digital is a copy.

Free everyday scans are for eligible pages. A box of archives is a batch/Pro conversation.

Receipts, contracts, and homework are different QA

Receipts: the date, total, and merchant name must be readable at 100% zoom. Tax auditors do not care about your artistic crop. If the total is in the curl, unroll and reshoot.

Contracts: every initialed clause and the signature block. Skew makes OCR and humans misread decimals. Two-sided prints need two captures; do not assume show-through is “page 2.”

Homework: teachers reject cuts that hide the name line. Include the header. If the assignment is a booklet, scan in reading order, not in the order the pages fell on the bed.

File size after scanning

Phone cameras produce 8MB JPEGs of a 4-inch receipt. Compress the PDF packet once on /tools/compress-pdf after merge. Do not Maximum-compress a contract you still need to print at a lawyer’s office.

Perspective, glass, and bound pages

A scanner app that “finds the page” can lock onto a placemat instead of the receipt. If the overlay rectangle is wrong, cancel and recapture rather than hoping a warp will un-crumple physics. Glass tables double the page; use paper or a matte folder as a backing. Bound homework that will not lie flat needs two slightly overlapping captures or a gentle weight on the opposite page — do not break the spine for a LMS upload.

Passports and IDs have glare from laminate. Tilt until the hologram is not a white blob, but keep all four corners. A pretty crop that loses the machine-readable zone is a failed scan even if the portrait looks fine.

Privacy of bank slips and IDs

Receipts contain card tails and addresses. Instant paths are the default I want for that. Convertify4u does not sell scans. Never upload someone else’s passport “to test the tool.”

If edges fail on a dark table or a page is always skewed, /contact with paper type (thermal, glossy, book) and Instant vs cloud — not the bank statement. Safaat Rahman Siham will take a lamp recapture over a warped PDF that a portal stamps illegible.

What the browser scanner actually saves

The page is a perspective and contrast tool. Magic Color is one of the filters, and it boosts contrast and color. It does not invent ink that a curled thermal receipt never captured. Fill the frame, leave the corners, and reshoot if the overlay grabs the placemat instead of the paper.

The image download is a PNG. The PDF download is a single A4 portrait page, with the scan placed as a JPEG at quality 0.92. That is one sheet, not a multi-page packet. For an expense report, scan each receipt, download each PDF, then join them in date order on the merge page. A set of PDFs at or under 100 MB can merge in the browser. If the packet is then too heavy for a portal, compress once, with Light first when the text still has to be read.

Do not expect this scan to become searchable Word by itself. If you cannot highlight words, the picture needs OCR, and that is a separate step. Keep the paper until the reimbursement clears. The scan is a copy you can file, and the PNG or one-page PDF is the file you can actually attach.

Free server follow-ups, when a later step uploads, are 8 a day and 12 MB. The scan canvas itself runs in the browser. If a cloud job is involved, uploads are deleted after processing, typically within one hour and no later than 24 hours.
