Frequently asked questions
About PDF Compressor and how Tarumak Studio works.
How much can the file size be reduced?
Typically 20–70%, depending on content. PDFs heavy with high-resolution images compress the most.
Will text remain readable after compression?
Yes — text in PDFs is vector-based and is not affected by compression. Only embedded images are resampled.
Can I choose the compression level?
Yes — a quality slider lets you balance file size reduction against visual quality.
Is PDF Compressor really free?
Yes — completely free, with no usage limits, no watermarks and no premium wall. Every tool on Tarumak Studio is free to use.
Do I need to create an account?
No. There is no sign-up, no login and no email required. Open the tool and use it immediately.
Are my files uploaded to a server?
No. PDF Compressor runs entirely in your browser — your files are processed locally and never uploaded, which also makes it faster than server-based alternatives.
What formats does it support?
PDF Compressor works with PDF.
Does it work on mobile?
Yes. The tool runs in any modern browser on desktop, tablet or phone — no app install needed.
