When You Need PDF Compression
Government portals in Nepal (IRD, DoTM, OCR) and job sites often enforce strict file-size limits. Email providers typically cap attachments at 25 MB. Compressing images inside a PDF is the fastest way to meet these limits without retyping or recreating the document.
Frequently Asked Questions
How much can a PDF be compressed?+
Compression depends on how image-heavy the PDF is. Text-only PDFs compress very little, while image-heavy files can shrink 50–80%. The tool balances image downsampling with text sharpness.
Will text stay selectable after compression?+
Yes. Text remains selectable and searchable. Only images are downsampled and metadata is trimmed.
Is my PDF uploaded to a server?+
No. Everything happens in your browser using pdf-lib. Your files never leave your device.
What is the best size to compress to?+
For email attachments, aim for under 2 MB. For government portals in Nepal, check the specific limit — many accept up to 1 MB or 500 KB.
