Guides
Start with the file you have and the result you need.
These worked examples explain which tool fits, what to check and where a conversion can lose information. The numbers are examples, not requirements for every recipient.
Combine several documents into one readable PDF
Use Nelvumo Docs for existing PDFs and JPEG or PNG pages. For example, a one-page cover letter, a two-page CV and two certificate photos should become a five-page PDF. Use Scan first if a photo needs its paper edges straightened.
- Open the sources together. Check the page count and rotate sideways pages before deciding the final order.
- Arrange the thumbnails in reading order. Remove duplicates deliberately; a printed page number does not change when you move its page.
- Save all five pages as PDF, then reopen the downloaded copy. Check names, dates, small text and the last page before sending it.
If the recipient needs searchable text, keep existing text PDFs as PDF. Photos remain pictures without OCR. A rectangle drawn over private text does not securely redact it, and a visual signature does not certify identity.
Prepare a photo for an upload form
Use Nelvumo Images when a form specifies pixels, shape, format or file size. Suppose it asks for a square 600 × 600 JPG below 200 kB: dimensions and bytes are separate requirements, so resizing alone may not be enough.
- Read the form’s exact requirements and enter them in the workspace. Choose a source with enough detail for the requested dimensions.
- Position the square crop so it keeps the subject. Choose JPG and the byte limit; changing the format can also change transparency.
- Create the result and read each requirement’s status. Inspect the downloaded picture at its actual size, then submit that copy yourself.
If the target cannot be met, check the missed bound instead of repeatedly exporting. Enlarging a small photo cannot restore detail. The tool checks file properties, not official rules about pose or lighting. Removing metadata also leaves everything visible in the picture.
Turn photographed paper into a readable PDF
Use Nelvumo Scan when the paper in a photo is tilted or surrounded by a table. For example, three photos of a letter should become three upright pages. Docs can combine images, but Scan lets you correct the paper corners and choose a cleaning look.
- Photograph flat paper with all four corners visible and even light. Check focus before importing; glare and blur cannot be repaired by cleaning.
- Check every suggested corner and move it to the paper edge if needed. Compare the cleaned preview with Original, especially around faint writing and coloured stamps.
- Put the three pages in order. If the portal has a PDF size cap, enter it in Save, read any quality reductions and inspect small text in the downloaded PDF.
If pale text disappears, switch that page back to Original or choose a gentler look. Retake a blurred or glared photo. The PDF contains page images without OCR; straightening a flat page does not flatten curved book paper.
