Almost every official process eventually asks for a PDF: application documents, ID scans, receipts for expenses, a portfolio of your work. If all you have are phone photos, you need to bundle them into one PDF without losing quality — and without uploading sensitive documents to some stranger's server. Here's how to do it right.
Step-by-step: images to PDF
Upload your images
Open the image-to-PDF tool and drop in your JPG or PNG files — as many as you need, in any order.
Arrange the pages
Use the up/down arrows to put pages in the right order, and remove any photo you don't want in the final document.
Pick a page size
Choose A4 for printable, official-looking pages, or Fit image when the PDF is for screen viewing only.
Generate & download
Hit Generate PDF and save the file. Everything ran in your browser — nothing was uploaded anywhere.
A4 vs fit-to-image — which page size?
| Page size | Best for | What happens |
|---|---|---|
| A4 | Job applications, visa/ID documents, anything that may be printed | Every photo is placed on a standard A4 page — uniform, professional, prints perfectly |
| Fit image | Portfolios, photo collections, screen-only sharing | Each page matches its photo's exact dimensions — no white borders, no stretching |
Rule of thumb: if a human might print it or an official portal expects documents, use A4. If it's a visual collection meant to be viewed on screen, Fit image looks far better.
Keeping quality high
- Start from the best source. A PDF can only be as sharp as the photos you feed it — use the original camera shots, not copies that already went through WhatsApp or a messaging app.
- Shrink before, not after. If the final PDF must stay under a portal's file-size limit, compress the images first to a sensible size, then build the PDF — don't build a giant PDF and try to squeeze it later.
- Photograph documents straight-on. For scans of paper, shoot from directly above in even light. Crooked, shadowy photos make the whole PDF look unprofessional no matter the settings.
- One image per page. Resist cramming four photos onto one page unless the form asks for it — single-image pages stay readable when zoomed.
Common mistakes
- Mixing orientations randomly. A PDF that flips between portrait and landscape photos feels chaotic — crop or rotate consistently before converting.
- Uploading PNG screenshots as-is for print. Screenshots are low-resolution by nature; on an A4 page they'll look soft. Fine for screen PDFs, risky for printed ones.
- Forgetting page order. Upload order isn't always the order you want — take ten seconds to arrange pages with the arrow controls before generating.
- Sending sensitive scans through server-side tools. Many free converters upload your files. EzySize builds the PDF locally in your browser, so IDs and certificates never leave your device.
