Can I take photos directly with my smartphone camera?

Yes. On mobile devices, clicking 'Take Photo with Camera' triggers your phone's native camera app. Once captured, the photo is immediately loaded into the browser cropping tool.

How does the auto-enhance feature improve scanned documents?

Our client-side canvas algorithm analyzes color histograms, increases contrast by 10%, and elevates brightness thresholds. This whitens yellowish paper backgrounds and darkens faint handwritten ink.

Can I change the order of pages before downloading the PDF?

Yes. All uploaded photos appear in the queued list. Simply click the Up and Down arrow buttons next to any page to reorder pages before compiling.

What image formats are supported?

The tool supports all standard image formats including JPEG (.jpg, .jpeg), PNG (.png), and modern WebP (.webp) files.

Can I fit images to full page without white margins?

Yes. You can select 'Fit to Image' from the Page Size dropdown menu. In this mode, each PDF page dimensions will match the exact aspect ratio of the underlying photo.

Is there a limit on how many images I can convert into a single PDF?

There are no artificial software limits. We recommend batches of up to 30 images at a time on mobile devices to ensure smooth browser performance.

Is this image scanning tool free to use?

Yes. The tool is completely free with no registration, no daily conversion limits, and zero watermarks added to your documents.

Important Caveats

Technical Boundaries & Scanning Guidance

Key advice regarding low-light resolutions, perspective skews, and batch sizing.

Camera Resolution Threshold

Photos taken in low-light environments with resolutions below 150 DPI may look pixelated when printed on physical paper. Natural lighting produces the best scanning output.

Tip:Ensure good ambient lighting and hold the phone camera flat parallel to the document.

Perspective Distortion Requires Rectangular Cropping

Severe angle tilts cannot automatically straighten trapezoidal desk distortions. The interactive cropping tool assists in trimming edges, but flat shooting is recommended.

Tip:Position the paper on a dark, contrasting background before shooting.

Memory Limits on 50+ Raw High-Resolution Images

Smartphone camera photos frequently exceed 12 megapixels each. Compiling more than 50 raw photos in a single batch may test mobile browser memory limits.

Tip:Compile large document sets in batches of 15 to 25 pages for optimal speed.

Output PDF is a Raster Image Document

Image to PDF places pictures inside PDF pages; it does not automatically perform Optical Character Recognition (OCR) to convert printed text into selectable typography.

Tip:If you need selectable text, ensure clear contrast so OCR tools can parse the output.
