Tips for Best PDF Quality

Check File Size: Most government portals have a PDF size limit of 1MB to 5MB. If your PDF is too large, compress the images before converting.

Common Problems & Fixes

PDF file size is too large after conversion
Compress your images before converting. Use our Image Compressor to bring each image under 100KB. A 10-image PDF with 100KB images will be around 1MB — well within most portal limits.
Images appear rotated in the PDF
Phone camera photos often have rotation metadata. Rotate the image to the correct orientation before uploading, or open it in any photo editor and save again — this resets the rotation data.
Text is not readable in the converted PDF
The resolution of the original photo is too low. For documents (Aadhaar, marksheets), scan or photograph at 150+ DPI in good lighting. Avoid photographs taken at an angle.
Portal rejects the PDF saying "not a valid PDF"
Open your generated PDF in Chrome browser → Print → Save as PDF. This re-exports as a widely-compatible PDF version that all portals accept.
