Quick Tips
- Use “Fit to Image” page size when you want to preserve each image's exact pixel dimensions instead of A4/Letter.
- Hover over a thumbnail to reveal the reorder and remove controls — there's no drag-and-drop.
- Choose “None” margin for full-bleed photo pages or “Medium” for document-style layouts.
- If a source image has transparency, check the output — transparent areas are flattened since the PDF embeds JPEGs.
What This Tool Actually Does
This converter builds a PDF from your images using jsPDF, entirely in your browser. Each image becomes one page, scaled to fit your chosen page size and margin, or sized to match the image itself in Fit to Image mode. Reordering happens through hover-revealed up/down arrows on each thumbnail — not drag-and-drop.
One detail worth knowing: every image is embedded as a JPEG regardless of its original format. That means a transparent PNG will lose its transparency in the output, flattened to a solid background instead. For ordinary photos, receipts, and scans this has no visible effect — it mainly matters for logos or graphics with a transparent background.
How to Convert Images to PDF Online
- Add your images. Open the converter above and drop in JPG, PNG, or WebP images, or click to browse. You can add multiple images at once.
- Reorder if needed. Hover over an image and use the up/down arrow buttons to change its position in the final PDF.
- Choose layout options. Pick a page size (A4, Letter, or Fit to Image), orientation, and margin.
- Convert. Click Convert to PDF. Each image is placed on its own page, scaled and centered based on your settings.
- Save. The finished PDF downloads automatically as images.pdf.
Real-World Examples
Expense Receipts
Photograph each receipt, add them in order, and convert to one PDF for an expense report instead of attaching several separate photos.
Scanned Assignment Pages
Combine photographed homework pages in the right order using the reorder arrows before submitting as one file.
Property Listing Photos
Use Fit to Image so each photo's own aspect ratio is preserved rather than being letterboxed onto an A4 page.
ID or Document Scans
Combine the front and back of an ID card into a single two-page PDF for a form that only accepts one file.
Common Mistakes
- Expecting drag-and-drop reordering — use the hover arrow buttons instead.
- Converting a transparent PNG logo and being surprised the transparency is gone.
- Using A4/Letter for a panoramic photo and getting a lot of empty margin space — try Fit to Image instead.
- Not checking image order before converting, then having to redo the PDF.
Best Practices & Expert Tips
- Use Fit to Image for photos and scans where preserving the original aspect ratio matters most.
- Use A4/Letter with Medium margins for a more document-style, print-ready look.
- Add all your images first, then reorder once, rather than reordering repeatedly mid-batch.
- Compress the final PDF afterward if it needs to fit a portal's size limit.
Why Use This Image to PDF Converter
No Upload to Any Server
Your images never leave your device. All conversion happens locally in your browser using jsPDF.
Combine Multiple Images
Add as many images as you need and combine them into a single, organized PDF, one image per page.
Custom Page Layout
Choose from A4, Letter, or Fit to Image page sizes, set portrait or landscape orientation, and adjust margins.
Reorder Before Converting
Use the hover arrow controls to move images up or down, or remove one from the batch entirely.
Privacy & Security
Images are assembled into a PDF locally in your browser using jsPDF — nothing is uploaded to a server to complete the conversion, which matters for personal photos, ID scans, and receipts.
Tool Limitations
- Reordering is hover-and-click, not drag-and-drop.
- All images are re-encoded as JPEG — transparency and some fine detail can be lost.
- Accepts JPG, PNG, and WebP only.
- Fit to Image assumes 96 DPI when converting pixel dimensions to a physical page size.

Frequently Asked Questions
Can I reorder images before converting them to PDF?
Yes. Hover over any image thumbnail and use the up/down arrow buttons to move it. There is no drag-and-drop reordering — the hover arrows are the way to change image order.
What image formats can I convert to PDF?
JPG, JPEG, PNG, and WebP are supported as inputs. You can mix formats in the same batch.
Will a PNG's transparent background stay transparent in the PDF?
No. Every image is embedded into the PDF as a JPEG, and JPEG has no transparency channel, so a PNG's transparent areas will be flattened to a solid background color rather than staying see-through. If you rely on transparency, check the output before using it for anything design-sensitive.
What does "Fit to Image" page size do?
It creates a PDF page sized to match the image's pixel dimensions (assuming a 96 DPI conversion), rather than fitting the image onto a standard A4 or Letter page. Use this when you want the page shape to match the photo exactly instead of adding letterboxing.
Can I choose portrait or landscape orientation?
Yes, for A4 and Letter page sizes. Orientation is not selectable in Fit to Image mode, since the page shape is derived directly from each image's own dimensions.
Does this tool upload my photos to a server?
No. Images are read and assembled into a PDF locally in your browser using jsPDF — files are not sent to a server to be converted.
Is there a limit on how many images I can combine?
There's no fixed limit set by the tool. Since everything runs in your browser, a very large batch of high-resolution images depends on your device's available memory rather than a server-side cap.
Will each image be on its own page?
Yes. Every image you add becomes exactly one page in the output PDF, in the order shown in the image list.
What's the difference between margin settings?
None uses the full page with no border. Small and Medium add increasing white space around each image, useful for a more document-like or print-ready look.
Can I remove an image after adding it, before converting?
Yes. Hover over the thumbnail and use the remove (X) button to drop it from the batch.
Does converting reduce image quality?
Every image is re-encoded as JPEG when it's placed into the PDF, which is a lossy format. For most photos this isn't visually noticeable, but a very high-quality PNG source will lose some fidelity in the process.
Can I use this for scanned documents or receipts?
Yes. This is one of the most common uses — photographing or scanning a document as an image, then combining several pages into one PDF for submission or archiving.
Can I use this on mobile?
Yes, the interface is responsive, though converting many high-resolution photos may be slower on an older phone than on a desktop.
Is my PDF saved anywhere after I close the tab?
No. The PDF is generated and downloaded directly to your device; nothing is retained in a server-side account or database.
What happens if an image fails to load?
The tool shows an error and skips that file, letting you continue with the remaining images. Check that the file is a valid JPG, PNG, or WebP.
