Convert Image to PDF →Common Use Cases
- Visa and document submissions: Many online portals require documents in PDF format. If you have a scanned photo of a document, convert it to PDF before uploading.
- University applications: Academic certificates, transcripts, and ID scans often need to be submitted as PDFs.
- Email attachments: A PDF is smaller and more universally readable than sending a raw image file.
- Combining with other documents: Once in PDF format, your image can be merged with other PDFs using a dedicated PDF editor.
Tips for Best Results
- Use a high-resolution image: Photos taken on a modern smartphone (at least 3 megapixels) produce sharp, readable PDFs. Very small images may appear blurry when scaled to A4.
- Good lighting matters: If you are scanning a physical document with a phone camera, ensure even lighting and hold the phone parallel to the page to avoid perspective distortion.
- Black-and-white photos: If your image is a scanned document (not a photo), converting to greyscale before uploading can reduce file size significantly.
- File size: If your original image is very large (over 10 MB), consider compressing it first using a free tool — the PDF output will be cleaner and faster to share.
Frequently Asked Questions
Is my image stored after conversion?
No. The image is deleted from our server the moment your PDF download begins. Nothing is stored or logged.
Can I convert multiple images at once?
Currently the converter handles one image per conversion. For multi-image PDFs, convert each image separately and combine them using a PDF editor.
What page size will the PDF be?
The image is placed on an A4-sized page and scaled to fit. The original image aspect ratio is preserved.
Does the converter work on mobile?
Yes — the converter works on any device with a browser, including phones and tablets.
