Compression levelOutput page size

This method recreates each page as a compressed image. The new PDF may not preserve selectable text, links, form fields, or embedded layers.

Reduce PDF file size in your browser

This compressor rebuilds PDF pages at a lower image resolution and JPEG quality, which can help reduce the size of scanned and image-heavy PDFs. Choose a lower compression level for clearer pages or higher compression for a smaller file.

Will this preserve editable PDF text?

No. This browser-based compression method creates image-based pages, so selectable text, links, fields, and layers may not remain editable in the output. It is best suited for visual documents and scans.

Are my PDF files uploaded?

No. All processing happens locally in your browser. Your original PDF is not uploaded to an EditGenApp server.

How to reduce PDF size without losing important detail

What this tool does

This tool reduces the size of image-heavy PDFs such as scanned certificates, photos, presentations, and printed forms. It is for people who need to send a document by email, upload it to a portal, or save storage space. It works by rebuilding pages with lower image resolution and quality settings.

How to use it

1. Choose one PDF file from your device.
2. Select Low for clearer pages, Recommended for a balance, or High when file size matters most.
3. Keep original proportions unless the receiving portal specifically requires A4.
4. Compress the file, compare the file-size result, and open the downloaded PDF to check readability.

Practical example

If a 12 MB scanned application PDF will not upload to a 5 MB portal, try Recommended first. Read the smallest text and check signatures or stamps. If they are unclear, repeat using Low compression rather than sending an unreadable document.

Who it is for

Use this tool when you need a quick, understandable result or document draft. Review the final output carefully before submitting, sharing, or relying on it.

Privacy and limitations: The PDF is processed locally in the browser and is not uploaded to an EditGenApp server. Do not use shared or public devices for confidential documents, and always check the downloaded file before sharing it.

Frequently asked questions

Will text remain selectable?

Not always. This browser-based method recreates pages as images, so selectable text, links, form fields, and layers can be lost.

Why did my PDF not become much smaller?

Text-only PDFs are already compact. Compression works best on scans and PDFs containing large images.

Can I compress a password-protected PDF?

No. Remove password protection only if you are authorised to do so, then use the tool.
