Some portals require PDFs under 300 KB — especially for online government or visa applications. Here is how to reach that target.
Go to pdfeditor.onl/compress-pdf. Select Strong compression. For most PDFs, Strong achieves 70–90% size reduction — bringing a 2 MB PDF down to 200–600 KB.
Tip: For a PDF that is still over 300 KB after Strong compression, the file likely has high-resolution images or many pages. See the next steps.
If compressing a multi-page document, use pdfeditor.onl/organize-pdf to remove unnecessary pages. Fewer pages directly means smaller file size after compression.
If the document must stay under 300 KB and still exceeds that after compression, split it into multiple parts at pdfeditor.onl/organize-pdf. Submit each part separately if the portal allows.
Scanned PDFs are image-heavy. Use Strong compression — it significantly downsizes image resolution while keeping text readable on screen.
