JPEG, PNG, WebP, GIF, TIFF, AVIF — up to 10 files, 25 MB total
2. Configure settings
PDFs will be re-serialized with object stream compression — a lossless technique that removes redundant internal objects and reduces file size without affecting content or quality.
Free plan: up to 10 images per batch. Upgrade for more.
What this tool does
Papiral compresses PDFs by re-serializing the internal document structure and enabling object streams — a lossless compression approach that removes redundant objects, reduces cross-reference table size, and results in smaller files without touching embedded images or fonts.
Problems it solves
- Reducing PDF file size before emailing to clients or uploading to a portal
- Compressing a batch of reports to meet an email attachment limit
- Shrinking PDF size for storage cost reduction
- Reducing file size of exported PDFs from design tools
Example
Compress 20 quarterly report PDFs before emailing to investors
Frequently asked questions
How much size reduction can I expect?
Results vary by document. PDFs with lots of redundant objects or unoptimized cross-reference tables see the largest reductions. Image-heavy PDFs may see only modest savings with this lossless approach.
Does this affect image quality inside the PDF?
No. Papiral's compression is lossless at the structure level — it does not re-encode embedded images, so quality is fully preserved.
