Best Practices for Image to PDF Conversion
Follow these tips to get the cleanest possible results:
- Preparation: Crop any unnecessary background from your images (like table surfaces around a receipt) before uploading. You can use our Smart Crop tool for this.
- Order: Name your images before uploading to ensure the correct order, as they are added in the same sequence you select them.
- Orientation: Choose landscape for wide images so they fit better without excessive scaling.
Why Use This Tool
- Unlike many online converters that upload your files to a server, this tool processes everything locally in your browser, making it a safer choice for sensitive documents like invoices, IDs, or scanned contracts.
- It combines multiple images into a single, print-ready PDF with flexible page size and orientation controls, saving you the extra step of using separate merging software.
- Because there is no upload step, conversion also starts instantly and works even on a slow or unreliable connection — the only network requests are for loading the page itself, not for transferring your photos back and forth to a remote service.
Advanced Usage Tips
- Batch scanning workflow: Photograph each page of a physical document with your phone, transfer the images to your computer, then upload them all here in one pass to produce a single multi-page PDF ready for email or archiving.
- Consistent aspect ratios: If your images vary widely in size, cropping them to a similar aspect ratio beforehand (with a tool like Smart Crop) helps the automatic fitting look more uniform across pages.
- Choosing Legal vs A4: Legal-size pages are taller than Letter and can be a better fit for very tall receipts or long screenshots, reducing the amount of empty margin around the content.
- Mixing formats: You can freely combine JPG, PNG, and WebP images in the same conversion — the tool decodes each one and treats it identically once loaded, so format differences never affect the final layout.
- Re-ordering after upload: If you added images in the wrong order, it is often faster to remove the misplaced ones and re-select all the files again with corrected filenames than to try to fix ordering after the fact.
Frequently Asked Questions
Is my data safe when converting images to PDF?
Yes. All conversion happens entirely in your browser using JavaScript. Your images are never uploaded to any server — they stay on your device throughout the process.
What image formats are supported?
You can upload JPG, PNG, and WebP images. They can be freely mixed within the same PDF — for example, combining scanned JPG receipts with a PNG screenshot.
Is there a limit to how many images I can add?
There is no hard-coded limit. Since everything runs in your browser, the practical limit depends on your device's available memory when handling very large batches of high-resolution images.
Can I change the order of images after uploading them?
Images are added to the PDF in the same order you select them. To control the final order, name your files sequentially (e.g., page-1.jpg, page-2.jpg) before selecting them.
Will my images be compressed or lose quality?
No unnecessary compression is applied. Images are scaled only as needed to fit the chosen page size, preserving their original sharpness and detail.
Which page size and orientation should I choose?
A4 is the standard choice for most documents outside the US, while Letter and Legal are common in the US. Use landscape orientation for wide images so they fit the page without excessive scaling.
