Balanced compression and quality
Batch Compress
Add multiple PDFs to compress at once
How It Works
Upload multiple PDFs
Drag in up to 100 files at once. Mix different file types if you need batch conversion.
Choose the operation
Select: compress all, convert all to Word/JPG/text, merge in order, or split all by page range.
Download all results
Processed files download as a ZIP. Batch operations on 50 files complete in under a minute.
Why SynthPDF?
Process 100s of files at once
Upload 100 PDFs and compress, convert, or watermark them all with one click — not one at a time.
ZIP download of all results
All processed files are packaged into a single ZIP for easy download and archiving.
Consistent settings
Apply the same compression level, watermark, or conversion setting uniformly to every file in the batch.
Error reporting
Files that fail processing are clearly reported with reasons — so nothing silently gets missed.
Secure batch processing
Files processed over HTTPS, deleted immediately after download. Batch operations don't store any file content.
Saves hours
Manual one-by-one processing of 50 files takes 30+ minutes. Batch processing finishes in under a minute.
