Client-Side OnlyWhat Is Image to PDF Conversion?
Converting images to PDF places one or more pictures onto pages inside a single PDF document, in the order you choose. It's the standard way to turn a handful of photos say, scanned pages, receipts, or a photo series into one file that's easy to share, print, or archive, instead of sending several separate image files.
NexaTools Image to PDF Converter builds the PDF file directly inside your browser using JavaScript. Each image you upload becomes its own page, and you can drag the order around before converting.
How to Convert Images to PDF Step by Step
Converting your images takes just a few moments. Follow these steps:
Upload your images
Drag and drop one or more JPG, PNG or WebP files into the upload area, or click to browse your device.
Reorder if needed
Use the ▲ ▼ buttons next to each image to arrange the page order exactly how you want it.
Pick a page size
Choose A4, Letter, or Fit Image to match the page size to each picture.
Convert & download
Click "Convert to PDF", then download your combined PDF file instantly.

Office workers turning whiteboard photos or printed forms into an archivable PDF.

Common Use Cases
Here are a few everyday situations where converting images to PDF comes in handy:
Assignment submission
Combine photographed pages of handwritten work into one PDF to upload.
Expense tracking

Portfolio sharing

Document archiving

Privacy: Why Browser-Based Conversion Matters
Many online PDF converters require uploading your images to a remote server before returning a result, which means your files briefly or sometimes permanently live on someone else's infrastructure. NexaTools Image to PDF Converter avoids that entirely. The PDF is assembled locally using JavaScript running in your browser, so your images never leave your device, there's no server round-trip, and nothing about your files is logged or stored anywhere.
Tips for Getting the Best Results
1. Upload images in roughly the order you want
While you can reorder pages with the ▲ ▼ buttons, starting with files already close to your desired order saves a few clicks.
2. Use "Fit Image" for mixed-size pictures
If your images have very different aspect ratios, "Fit Image" avoids extra white margins by matching each page exactly to its picture's dimensions.
3. Use A4 or Letter for a document-style PDF
For a PDF meant to look like a traditional document or be printed, A4 or Letter centers each image on a consistent standard page size.
4. Keep image count reasonable per batch
Very large batches of high-resolution photos take longer to process since everything runs in your browser split into smaller batches if needed.
Common Problems & Troubleshooting
Running into an issue while converting your images? Here are fixes for the most common problems:
⚠️ "Could not read this image"
The file may be corrupted or in an unsupported format. Confirm it's a valid JPG, PNG, or WebP file and try again.
⚠️ Pages are in the wrong order
Use the ▲ ▼ buttons next to each thumbnail in the list to move pages up or down before converting.
⚠️ File larger than 20 MB
Very large images aren't supported in-browser. Try compressing the image first, then add it to your PDF.
⚠️ PDF looks too zoomed in or has large margins
Switch the page size option to "Fit Image" so each page matches its picture exactly, instead of centering it on a fixed A4 or Letter page.
⚠️ Conversion is slow
A large number of high-resolution images takes longer to encode since everything runs locally. Try converting in smaller batches.
⚠️ Download button doesn't work
Some browsers block automatic downloads from JavaScript. Check your browser's download permissions or pop-up settings for this site.
