Convert images to PDF, locally
Someone snapped 5 receipts on their phone and needs one PDF for an expense form. Here's the easy way — your photos never leave your device.
- JPG, PNG, WebP supported
- A4, Letter, Legal page sizes
- 10 receipts → 1 PDF in ~1 second
- Reorder freely before exporting
Drop, reorder, download a PDF.
Same Combine tool handles images — just drop image files instead of PDFs.
Open the Combine tab
Same tool that merges PDFs — accepts images too.
Drop your images
JPG, JPEG, PNG, or WebP. Drag or click to browse.
Order them
Drag cards to reorder. For receipts, date order; for screenshots, reading order.
Pick A4, Letter, or Legal
Default is A4. Each image is centred on its page, scaled to fit without cropping.
Combine and download
Your browser does the work — no upload. Output is one PDF with one image per page.
Common formats in. One PDF out.
HEIC, TIFF, RAW don't work directly — convert to JPG first.
JPG / JPEG
The most common. Phone photos, scanned receipts, screenshots.
PNG
Lossless. Good for screenshots with text or UI.
WebP
Modern format. Smaller files, same quality.
Mixed formats
Drop a JPG and a PNG in the same session. Both combine fine.
A few things I've learned.
From converting receipts to PDF over the years.
Take photos in good light
Daylight from a window is best. The PDF inherits photo quality.
Crop tight first
Removing background reduces file size 30–50% and looks more professional.
Use A4 portrait for receipts
Most accounting software expects this. Letter is fine for US.
Margins matter for printing
Normal margins (0.75 in) for print. None for digital-only.
Receipts and IDs stay on your device.
The usual answers are: upload to SmallPDF (servers see your files), email images to yourself (clunky), or Adobe Acrobat ($25/month). A browser tool sidesteps all of that.
- Phone photos carry EXIF GPS — uploading exposes location
- Free services often watermark or cap at 3 images per session
- Some re-encode PNG → JPEG without asking
- pdf-lib embeds your images byte-for-byte — no re-encoding
- EXIF stays in the PDF; bytes never leave your device
- JPG, PNG, and WebP all combine in the same session
Honest about the limits.
A few cases where the browser approach falls short.
HEIC from iPhone
Browser can't read HEIC. AirDrop as JPG or use a HEIC-to-JPG converter first.
Adding text or captions
Not in Combine — output is image-only. Generate, then open in Edit to add text.
Compressing the output
PDFs add structural overhead. Compress images first if size matters.
Drag-to-reorder on mobile
Finicky on small screens. Desktop is easier for many files.
Common questions when converting images.
Will the PDF be smaller than the images?
Usually about the same or slightly larger. PDFs add structural overhead. Compress images first with TinyPNG or Squoosh if size matters.
Does the drop order matter?
Sets the initial order. You can reorder by dragging cards — output follows the final list.
Can I do this on my phone?
Yes. Works on mobile Safari and Chrome. Drag-to-reorder is finicky on small screens — for many files, desktop is easier.
What about HEIC from iPhone?
Browser can't read HEIC. AirDrop as JPG (iPhone share sheet offers this) or use any free HEIC-to-JPG converter.
