Compress PDF to 1MB

Reduce PDFs toward a 1MB target for job applications, attachments, and upload portals. Start with the 1MB target already filled in and export a smaller PDF without leaving the browser.
Works with PDF files.

{{ pdfFile.name }}

Pages: {{ pageCount }}
Size: {{ sizeLabel }}
We aim for your target, but text-heavy or already optimized PDFs may not shrink much. Use Smallest size for the lowest output, or remove pages if you need to go lower.
Compression works best on scanned PDFs and image-heavy documents.
{{ warningMessage }}
Progress: {{ compressionProgress.toFixed(0) }}%
{{ targetStatus }}
Compressed size: {{ resultSizeLabel }}
Saved: {{ compressionRatio }}%
We gave you the smallest result from this pass, but the PDF stayed above {{ targetLabel }}.
This output uses the most aggressive compression pass on this page.

How to compress PDF to 1MB

Choose a PDF

Select a PDF, choose a preset, or fit to a target size like 500KB or 1MB.

Download the compressed file

Export a smaller PDF with a clear quality tradeoff note.

Preset and target-size workflows

Choose low, medium, or high quality, or fit the PDF under a target size.

Best for scanned PDFs

Compress image-heavy PDFs for email and uploads.

Target-size fitting

Aim for common size limits like 500KB or 1MB with clear best-effort messaging.

See size savings

Preview how much size you saved before downloading.

Quality tradeoff guidance

Clear messaging helps you pick the right compression level.

Browser-first processing

Compression runs in your browser on your device for privacy.

No installs required

Compress PDFs from any modern browser.

Frequently Asked Questions

Usually, yes. A 1MB target leaves more room for page detail and readability, especially on medium-length scanned PDFs.

Yes. The page starts with a 1MB target, but you can switch to preset compression or Smallest size at any time.

This workflow is strongest on scanned and image-based pages. Some text-native PDFs are already efficient and may not shrink much further.
