What JPG to PDF does
PDFGrover's JPG to PDF tool combines one or more images into a single PDF — one image per page, in the order you upload them. You control page size, orientation, and margins. It's called "JPG to PDF" because that's the dominant use case, but it accepts PNG files too.
When to convert images to PDF
- Scanned documents — phone photos of a contract, lease, or form turned into one tidy PDF instead of loose images.
- Receipts & expenses — bundle a trip's receipt photos into a single file for reimbursement.
- ID / document copies — front and back of a card on clean, consistently-sized pages.
- Photo sets & portfolios — share many images as one document that opens the same everywhere.
- Submitting where only PDF is accepted — applications and portals
that reject loose
.jpgfiles.
How to convert JPG to PDF
- Upload your images — drag them in or click to browse. They'll appear in the PDF in upload order.
- Set page size, orientation, and margins (see below).
- Click Create PDF and download the combined document.
Page, orientation and margin options
- Page size
- Fit to Image (default) — each page matches the image's pixel dimensions, so nothing is cropped or stretched.
- A4 (210 × 297 mm)
- Letter (8.5 × 11 in)
- Orientation — Auto-detect (chosen per image from its aspect ratio), or force Portrait / Landscape.
- Margins — None, 10 mm, 20 mm, or 30 mm, applied on all four sides when the page size isn't Fit-to-Image.
Image order
Images land in the PDF in the order you upload them — there's no post-upload reordering here. To control sequence, either select files in the order you want, or build parts and combine them with Merge PDF, which does let you reorder before merging.
Working with PNGs
- Transparent areas of a PNG are placed on a white background (standard image-to-PDF behaviour).
- If transparency matters or you're working only with PNGs, use PNG to PDF, which is tuned for that case.
Limits
- Up to 100 MB per image (JPG, JPEG, PNG)
- Up to 100 MB total per conversion
- No hard file-count cap, though browser memory gets tight beyond a few hundred photos in one go
Where it runs — and your privacy
Small batches assemble entirely in your browser (nothing uploaded) when you convert 10 images or fewer with a total size of 30 MB or less. Larger batches use our secure server, because doing that much image work in the browser is slow and memory-hungry. Server uploads go over HTTPS, the PDF is built, and the source images are deleted as soon as your download is ready. Close the tab mid-conversion and the job is cancelled and temporary files cleared automatically. No sign-up, no watermark, no copies kept.
Tips
- Name files in order (
1.jpg,2.jpg, …) so upload order is the page order you want. - Big result? Photo PDFs can be large — run it through Compress PDF before emailing.
- Want it editable later? This produces image pages (not selectable text). To make a scan searchable, run OCR PDF afterward.
Troubleshooting
- Pages out of order — re-upload the images in the right order, or combine parts with Merge PDF.
- Image looks stretched — use Fit to Image so each page matches the photo's dimensions.
- PNG transparency turned white — expected here; use PNG to PDF if you need it preserved.
- Upload rejected — check each image is under 100 MB and the batch total is within 100 MB.
