- 2Move the slider toward 'Smaller' for aggressive compression.
- 3Click Convert.
- 4Download your compressed PDF.
Many upload portals, job application systems, and email providers have a 1MB file size limit for PDFs. This is easy to hit with modern PDFs that include high-resolution images, multiple fonts, or scanned pages. Switch & Shrink uses Ghostscript-based compression to reduce PDF file size by optimizing embedded images and removing redundant internal data. Text remains crisp and searchable after compression. For PDFs with lots of embedded images, you can often get well under 1MB using the 'Smaller' setting. Text-only PDFs or already-optimized PDFs may see less dramatic reduction — but every bit helps when hitting a strict upload limit.
Frequently Asked Questions
Can every PDF be compressed to under 1MB?
PDFs with embedded high-resolution images can almost always be compressed to under 1MB. Text-heavy PDFs or PDFs that are already compressed may not reduce as much. We'll compress as much as possible.
Will my PDF still be readable after compression?
Yes. Text remains crisp and searchable after compression. Only heavily embedded images might show some quality reduction at aggressive compression settings.
Are watermarks added to compressed PDFs?
Never. Switch & Shrink is watermark-free.
