What image formats are supported?
JPG (JPEG) and PNG only. WebP, HEIC, HEIF, and AVIF files are rejected with an error message asking you to convert them to JPEG or PNG first.

About this tool
Platforms that require document submissions often only accept PDFs, not individual image files. Converting photos of filled forms, scanned receipts, ID documents, or multiple images into a single PDF is the standard workaround.
This tool handles JPG and PNG images and produces a ready-to-submit PDF - though WebP, HEIC, HEIF, and AVIF files are rejected outright, so iPhone photos (which save as HEIC by default) need converting to JPEG first.
This tool converts one or more JPG or PNG images into a single PDF, one image per page, in the order you arrange them - entirely in your browser, using the client-side pdf-lib library. Each page is sized to exactly match its source image's own dimensions, with no margins.
How to Use JPG / PNG to PDF Converter
Upload Images
Add one or more images in the order you want them in the PDF.
Arrange Pages
Adjust the image order before export if needed.
Generate PDF
Each image is embedded as its own PDF page.
Download PDF
Save the combined PDF instantly to your device.
Common Workflows
Upload Your Images
Upload one or more JPG or PNG images - WebP, HEIC, HEIF, and AVIF files are rejected with an error naming the unsupported format.
Arrange the Order
Use the reorder button on each image to move it earlier in the list - the images convert into pages in the order shown, top to bottom.
Remove an Image You Don't Need
Click the trash icon on any image to remove it from the list before converting.
Convert and Download
Click Convert to PDF to generate a single PDF with one page per image, which downloads automatically as "images-to-pdf.pdf".
Best For
- Converts any number of uploaded JPG or PNG images into a single PDF, one image per page, in the order shown in the list.
- Each output page is sized to exactly match its source image's own pixel dimensions and fills the page edge-to-edge - there's no fixed page size like A4 or Letter, and no margin setting.
- Processes entirely in your browser using the pdf-lib library - your images are never uploaded to any server, verifiable yourself via your browser's DevTools Network tab.
Examples
Converting 3 images in a specific order
Input
Uploaded: receipt-1.jpg (1200×1600px), receipt-2.jpg (1200×1600px), receipt-3.jpg (1600×1200px), in that orderOutput
One PDF with 3 pages - pages 1 and 2 sized 1200×1600pt (portrait), page 3 sized 1600×1200pt (landscape)Each page's dimensions exactly match its source image's own pixel dimensions - there's no shared page size across the document, so mixing portrait and landscape photos produces pages of different sizes and orientations.
Use Cases
Submitting scanned documents to a portal that requires PDF
Upload photos of each page in order and convert them into one submittable PDF.
Combining receipt photos into an expense record
Upload multiple receipt photos and convert them into a single PDF for an expense report.
Building a simple PDF portfolio
Upload a set of JPG or PNG images in your preferred order to create a one-image-per-page PDF portfolio.
Common Mistakes
Problem
Uploading WebP, HEIC, HEIF, or AVIF files
Solution
These formats are rejected outright with an error message - convert them to JPEG or PNG first, since this tool only accepts those two formats.
Problem
Expecting iPhone photos to work without conversion
Solution
iPhone photos saved in HEIC format are rejected - convert them to JPEG first using a HEIC to JPG converter.
Problem
Expecting a fixed page size like A4
Solution
There's no standard paper size - each page is sized to exactly match its source image's own pixel dimensions.
Problem
Being surprised by a sideways page
Solution
The tool doesn't read or correct EXIF orientation metadata, so a photo that relies on its EXIF tag to display upright may appear rotated on the page.
Problem
Trying to move an image later in the list
Solution
The reorder button only moves an image earlier - to move an image later, move the images ahead of it earlier instead, or remove and re-add images in your preferred order.
Tips & Best Practices
Convert HEIC photos to JPEG before uploading
If your photos are from an iPhone, run them through a HEIC to JPG converter first, since HEIC files are rejected here.
Check image orientation before uploading
Since EXIF orientation isn't auto-corrected, rotate any photo that appears sideways in its own viewer before adding it, rather than after converting.
Build the list in order rather than reordering extensively
Since the reorder control only moves images earlier, it's often faster to remove and re-upload images in your intended order than to reorder a long list.
Expect page sizes to follow your images
If you need uniform page sizes, resize your images to the same dimensions before uploading, since the tool doesn't normalize page size for you.
Limitations
Only JPG and PNG are supported
WebP, HEIC, HEIF, and AVIF files are rejected outright - convert them to JPEG or PNG before uploading.
No fixed page size
Each page is sized to exactly match its source image's own pixel dimensions - there's no A4, Letter, or other standard paper size option.
No margins
Images fill their page edge-to-edge with no margin setting available.
No EXIF-orientation correction
The tool embeds each image's raw pixel data without reading EXIF rotation metadata, so a photo relying on that metadata to display upright may appear sideways.
Reordering only moves images earlier
The reorder control moves an image up/earlier in the list - there's no corresponding "move later" control.
No stated file-count or size cap, but browser-memory-bound
There's no artificial limit on how many images or how large they can be, but since everything runs in your browser tab, very large or numerous images are limited by your device's available memory.
Comparisons
A Single Image vs. Multiple Images
Both go through the same conversion - the only difference is how many pages the result has.
| One Image | Multiple Images | |
|---|---|---|
| Output | A one-page PDF sized to that image's dimensions | A multi-page PDF, each page sized to its own source image |
| Ordering | Not applicable | Pages follow the order shown in the upload list |
| Best for | A single scanned page or photo that needs to be a PDF | Multi-page scans, receipt batches, or photo compilations |
Which should you use?
The conversion logic is identical either way - upload one image for a single-page PDF, or several in your intended order for a multi-page one.
FAQs
The most common question is what image formats are supported. Only JPG and PNG - WebP, HEIC, HEIF, and AVIF are rejected with a clear error message. If you're converting iPhone photos, convert them from HEIC to JPEG first. The FAQ below also covers page size, orientation, and where your images are processed.
Can I convert iPhone photos (HEIC) to PDF?
Not directly - HEIC files are rejected. Convert your HEIC photos to JPEG first using a HEIC to JPG converter, then upload the converted files here.
What page size does the output PDF use?
There's no fixed page size like A4 or Letter. Each page is sized to exactly match its source image's own pixel dimensions, with the image filling the page edge-to-edge - there are no margins.
Why is my photo sideways in the PDF?
This tool embeds each image's raw pixel data without reading or correcting EXIF orientation metadata. If a photo relies on its EXIF tag to display right-side up (common with phone cameras), it may appear rotated on the page - rotate the image file itself before uploading if this happens.
Is my document uploaded anywhere?
No. This tool processes your images entirely in your browser using the client-side pdf-lib library - your files are never uploaded to any server. You can verify this yourself by opening your browser's DevTools Network tab before converting.
