How many images can I convert to a single PDF?

You can upload and convert multiple images. Since the processing runs securely memory, it is highly efficient and limited only by your device's capacity.

Can I use PNG files as well?

Yes, our converter accepts PNG, JPG, and JPEG files. It automatically converts them to PDF pages and scales them appropriately.

Will my images retain their high resolution?

Yes, the tool preserves document aspect ratios and uses high-quality rendering, balancing quality and compression to meet target file sizes.

What exactly does the 400KB file size limit mean?

The 400KB size limit requires your document or photo to be strictly smaller than 409,600 bytes on disk. Government portals and application databases will automatically reject any upload that exceeds this exact byte capacity.

Can I compress a very large file (e.g. 5MB) down to 400KB?

Yes. Depending on the original file size, our local processing engine will apply aggressive JPEG quantization and iterative canvas scaling to mathematically ensure the final output file is under the 400KB target limit.

How to compress your file to 400KB

Recruitment portals like NSDL PAN, banking applications, and state public service commissions often require multiple marksheets or identity documents to be uploaded in PDF format rather than raw images. Our local JPG to PDF converter allows you to convert JPEG, JPG, and PNG scans into print-ready PDF files. The tool automatically adjusts dimensions and applies secure compression to make sure the output PDF stays under standard limits like 100KB, making it immediately ready for portal uploads. Large files can cause upload failures on strict portals or delay email delivery. Our advanced local processing engine ensures your file is shrunk to exactly 400KB.
