Is JPG/PNG to PDF really free?

Yes — no account, no paywall, no watermark added to the result.

Does my file get uploaded anywhere?

No. JPG/PNG to PDF runs entirely in your browser using pdf-lib/pdf.js — your file is never sent to a server.

Can I mix JPG and PNG files in one PDF?

Yes — add any combination and they'll combine into one PDF, one image per page.

Can I reorder the images before converting?

Yes — drag them into the order you want on the options screen before running the tool; that order becomes the page order in the finished PDF.

How is each page sized?

Each page is sized to match its image's own proportions, capped at a sensible maximum width, so a portrait photo produces a portrait page and a wide screenshot produces a wide page.

What happens if one of my files is corrupted or not really an image?

It's skipped automatically, and the final status message lists which file names were skipped, so the rest of the batch still converts successfully.

How many images can I add at once?

There's no fixed limit beyond your device's memory — add as many as you need in one pass.

Does this crop, rotate, or straighten my images?

No — images are placed exactly as they are. If you're photographing a physical document and need cropping, rotation, or a scan-style cleanup, use Scan to PDF instead.

Can I reorder pages after the PDF is created?

Not in this tool — reorder the images in the upload list before running it, since that order becomes final in the output. To reorder an already-made PDF, use Organize PDF.

Is the quality reduced?

Only if an image exceeds the maximum page width, in which case it's scaled down proportionally; smaller images are embedded at their original resolution.

How to Convert JPG or PNG Images to a PDF

Turn a stack of photos or scans into one multi-page PDF you can email, archive, or print — entirely in your browser.

A folder of receipt photos, screenshots, or phone scans is hard to email as twenty attachments. JPG/PNG to PDF builds one ordered multi-page document — each image on its own page — entirely in your browser.

Add JPG or PNG files, drag them into reading order, and download images.pdf. Pages size to each image’s proportions (with a sensible max width). Corrupt non-images are skipped with names listed in status.

When JPG/PNG to PDF is the right tool

Expense receipt packs

Photograph receipts through the week, reorder chronologically, and submit one PDF to finance.

Bug-report screenshot bundles

Stack UI screenshots into a single PDF reviewers can page through in order.

Application photo packets

Portals that want ‘one PDF of supporting images’ get a clean convert instead of a ZIP of loose files.

How to run JPG/PNG to PDF on TechDriven Tools

Open JPG/PNG to PDF.
Add JPG/PNG files — Mix formats freely; non-images are skipped automatically.
Drag to set page order — List order becomes PDF page order — fix it before you run.
Convert and download — Each image becomes a page sized to its aspect ratio.

Key options: Reorderable image list; mix JPG and PNG; per-image page sizing capped around 1200pt width.. Change one at a time when comparing.

Privacy on this workflow

Processing stays in your browser — ideal for confidential pages and photos.

Mistakes that waste time with JPG/PNG to PDF

Using this for crooked paper photos — It does not crop or deskew. Use Scan to PDF when you need cleanup.
Ignoring EXIF sideways phone photos — Rotate the image or fix the PDF page with Rotate PDF afterward.
Screenshotting a PDF to ‘convert’ it — Merge the real PDF instead of photographing it into images first.

Page sizing behavior

Portrait photos become portrait pages; wide screenshots become wide pages. Mixed aspect ratios in one PDF are normal on screen but can surprise printers — scale-to-fit when printing mixed sizes.

If you need a fixed Letter/A4 frame with margins, a word processor may fit better; this tool prioritizes image-true pages.
