Convert Images to PDF Online
The Tools Kit’s free Image to PDF converter turns one photo or a whole batch of images into a single PDF document, with one page per image in the order you add them. Use it to convert JPG to PDF, PNG to PDF, or a mix of formats, such as phone photos of a signed form, scanned receipts, or screenshots, into one file you can email, upload, or print.
The PDF is built inside your browser, so your images are never uploaded. There is no signup, no watermark, and no daily limit. If your files are all JPG photos, the dedicated JPG to PDF converter works too; the rest of the image utilities are collected on the image tools page.
How to Convert Images to PDF
- 1
Add your images
Click the upload area or drag and drop one or more images onto it. You can select several files at once and add more batches later; new images are added to the end of the list.
- 2
Check the order
Each image is listed by number and filename. The PDF pages follow this order, so remove any image you added by mistake or in the wrong place.
- 3
Build the PDF
Click Build PDF. Every image in the list becomes its own page, sized to that image’s dimensions.
- 4
Save the file
The finished document downloads automatically as images.pdf. Rename it afterwards if you need a different filename.
Pages follow the list order and there is no drag-to-reorder, so if order matters, add the images in sequence. Removing an image and adding it again moves it to the end of the list.
Supported Formats and Image Quality
A PDF can only hold image data in a few native forms, so each file is handled according to its type:
- JPG / JPEG — copied into the PDF byte for byte. There is no second round of JPEG compression, so photos keep exactly the quality they had.
- PNG — decoded and stored losslessly, including any transparency. Transparent areas show the PDF viewer’s page background, usually white.
- WebP, GIF, BMP and other formats — drawn onto a hidden canvas and converted to PNG first, then embedded. An animated GIF contributes only its first frame.
- HEIC — works only in browsers that can display HEIC images. Elsewhere, convert iPhone photos with the HEIC to JPG converter before adding them.
Because JPG data is not recompressed and everything else is stored losslessly, the PDF ends up at least roughly as large as the images combined, and WebP or GIF files converted to PNG can grow larger than the originals. If you need a small file for an email or an upload portal, shrink the photos first with the image compressor, or reduce the finished document with Compress PDF.
PDF Page Size: How Pixels Become Pages
This converter does not force images onto A4 or US Letter paper, so nothing is cropped, stretched, or padded with margins. Instead, each page takes the size of its image: the pixel width and height are used as the page size in PDF points, and a PDF point is 1/72 of an inch.
Page width in inches = image width in pixels ÷ 72. A 1200 x 1600 scan makes a 16.7 x 22.2 inch page, and a 3024 x 4032 phone photo makes a 42 x 56 inch page. On screen this makes no difference, because PDF viewers scale each page to fit the window. When printing, choose “Fit to page” or “Shrink to fit” in the print dialog so every page lands on a standard sheet. If you want uniform pages, bring the images to the same dimensions with the image resizer before converting.
Portrait images make portrait pages and landscape images make landscape pages. If a phone photo shows up sideways in the PDF, straighten it with the image rotator and add the rotated copy.
Privacy: Converting Images Without Uploading Them
Many online image to PDF converters upload your files to a server. Here, the open-source pdf-lib library assembles the PDF in your browser tab, so ID cards, bank statements, and medical paperwork stay on your device. One detail is easy to miss: because JPG files are embedded unchanged, any EXIF metadata inside them, including camera details and GPS location, is carried into the PDF as well. Strip it first with the EXIF remover if you plan to share the document widely.

Image to PDF terms explained
| Term | What it means here |
|---|---|
| PDF point | The unit of PDF page size; 72 points make one inch. This tool uses one point per image pixel |
| Lossless embedding | Storing an image in the PDF without throwing away detail; PNG images are stored this way here |
| JPEG passthrough | Copying the original JPEG data into the PDF unchanged, with no second round of compression |
| Re-encoding | Decoding an image and saving it again in a different format; formats such as WebP are re-encoded to PNG here |
| EXIF metadata | Camera details, date taken, and sometimes GPS location stored inside a photo file |
Frequently Asked Questions
Add the image to the upload area above by clicking it or dragging the file in, then click Build PDF. The image becomes a one-page PDF that downloads as images.pdf. It takes a few seconds and needs no account.
Select several images at once, or add them in batches, and they appear in a numbered list. Click Build PDF and every image in the list becomes its own page of a single PDF, in the order shown.
JPG and PNG are embedded directly. Other formats your browser can open, such as WebP, GIF, and BMP, are converted to PNG on a hidden canvas first and then embedded. An animated GIF contributes only its first frame.
Only if your browser can display HEIC images, which most desktop browsers other than Safari cannot. The reliable route is to convert the photos to JPG first with the HEIC to JPG converter, then add the JPG files here.
No. JPG files are copied into the PDF byte for byte, without being compressed a second time, and PNG files are stored losslessly. Formats such as WebP are converted to PNG, which is also lossless.
Each page matches its image instead of a fixed A4 or Letter size. The image’s pixel width and height are used as the page size in PDF points, where 72 points equal one inch, so a 3024 x 4032 phone photo makes a 42 x 56 inch page. PDF viewers scale it to fit the screen, and print dialogs can scale it to fit the paper.
Pages follow the order of the list, and there is no drag-to-reorder. To move an image to the end, remove it and add it again; for full control, add the images one at a time in the order you want.
No. The PDF is assembled in your browser tab with the pdf-lib library, so your photos, receipts, and scanned documents never leave your device.
Because JPG data is copied in unchanged and every other image is stored losslessly, the PDF is at least roughly as large as the images you added combined. WebP or GIF files can grow noticeably, since they are converted to lossless PNG. Compress the images before converting, or compress the finished PDF, to make it smaller.
It can. JPG files are embedded with their original bytes, which include any EXIF metadata such as camera details and GPS location. Strip that metadata from the photos first if you plan to share the PDF publicly.
There is no fixed limit, no watermark, and no signup. The practical limit is your device’s memory, since every image is held in the browser while the PDF is built.

How do you convert images to a single PDF?
To convert images to PDF, add one or more JPG, PNG, or WebP files in the order you want, then click Build PDF. Each image becomes its own page sized exactly to the image's pixel dimensions, and the combined file downloads as images.pdf. The PDF is built in the browser with pdf-lib, so nothing is uploaded.
Can you combine multiple JPG files into one PDF?
Yes. Select several JPG files at once, or drag them in one at a time, and each is added as a separate page in the order listed. JPG and PNG data is embedded directly without re-encoding, so photo quality is preserved; other formats such as WebP are converted to PNG first.
