PDF merge
Zip rejected? One PDF per photo rejected? Merge images into one file
The form said “upload one PDF.” You sent a zip, eight JPGs, or eight single-page PDFs. It still said no. The fix is a merge: many images in, one file out — not another archive, and not one PDF per photo.
Three uploads that look finished — and still fail
The signup, visa, or admin form asked for one PDF. You sent a zip of scans, dropped eight JPGs, or exported “one photo → one PDF” eight times. The backend still said no — not because the pages are wrong, but because it will not unpack an archive, walk a file list, or stitch eight PDFs for you.
| What you uploaded | What the form usually does |
|---|---|
A .zip of photos | Rejects it. Most portals do not unzip. They want a document, not an archive. |
| Several JPG / PNG files | Rejects extra slots, or only keeps the last file. “Multiple files” is not “one PDF”. |
| One PDF per image | Looks like you followed the format, still fails: they asked for one file, not a stack of PDFs. |
| Many images merged into one PDF | This is the path that matches “upload a single document”. |
Merge the pages, then download one file
Open Image711's Image to PDF. Decoding and page assembly stay in your browser; the originals are never uploaded. Drop several images, set the order, generate one PDF. Keep each source ≤ 20MB — that is a per-image cap, not a reason to zip them again.
- Drop the pages, not a zip: click or drag JPG / PNG / WebP / GIF (up to 50). If the folder is still a
.zip, unpack it first. HEIC that will not open should be converted — the HEIC to JPG guide covers the phone case — then come back. - Put the stack in review order: each row is one PDF page. Drag or use the arrows so ID front sits before ID back, then the rest. Landscape or upside-down pages: fix them in Rotate / Flip first, then merge. A sideways page in a portrait PDF is how a visa desk asks you to resubmit.
- Pick a page size, then generate one PDF: A4 portrait for most forms; A4 landscape if every scan is wide; auto-fit if you only need on-screen reading. Click generate and download one file — not one PDF per image.
The form asked for one document. Merge is the job: many images in, one PDF out. Keep each source under 20MB, straighten pages before you stack them, and stay local so an ID scan never leaves the device.
Straighten, crop, or shrink before you stack
Merge does not fix a crooked scan or a 15MB phone shot. Run this list before you generate:
- Sideways or upside-down: rotate first in Rotate / Flip, then drop the corrected files. Do not hope the PDF viewer will “just turn it” for the reviewer.
- ID photo still has extra sofa in the frame: crop the 1:1 or 1-inch box first — the ID crop guide — then put that JPG on its page.
- A single image is over ~20MB, or the PDF itself gets rejected as too large: hit a target KB first — the target KB guide — then merge the lighter JPGs.
- You need “for visa use only” on the pages: stamp the set with the watermark guide, then merge those copies.
The short version
Zip, a pile of JPGs, or one PDF per photo are three ways to miss “upload one file.” Unpack, rotate anything sideways, keep each image ≤ 20MB, merge into one PDF in order, and do it locally. That is the packet most signup and visa backends actually open.
About merging images into one PDF
Can I drop a zip straight into Image to PDF?
No. Unpack the zip first, then drop the images. Most signup and visa backends also refuse a zip — they want a document they can open, not an archive they have to extract.
I already made one PDF per photo. Why is that still rejected?
The form asked for one file. Eight single-page PDFs are still eight uploads. Put those pages — or the original images — into one merge and download a single PDF.
A page is sideways, or one image is huge. Merge first?
No. Rotate or flip sideways and upside-down shots first. Keep each source around 20MB or under. If the portal also caps the PDF size, compress the heavy JPGs to a target KB, then merge.
Are the original photos uploaded to a server?
No. Image711 assembles the PDF in your browser. The originals stay on the device; nothing is sent to an upload backend for processing.
