StuHub PDF Compressor vs Smallpdf — which is right for you?
Smallpdf is the category leader for online PDF compression — widely used, polished, and cloud-based. StuHub's PDF Compressor tackles the same job but runs entirely in your browser, never uploading your file, with no account and no per-day cap. The trade-off: Smallpdf has a richer feature set (signatures, redaction, desktop apps) that StuHub deliberately scopes out of for our launch release. Below is the side-by-side that lets you pick the right one for your workflow.
Feature-by-feature
Frequently asked
Is StuHub really free forever?
Yes. There is no paid tier; the site is ad-supported on content pages only. Tool pages stay ad-light and every feature is unlocked by default.
Will Smallpdf give better compression?
For image-heavy PDFs (scans, photo reports), Smallpdf's server-side pipeline often does squeeze more bytes out because it can re-encode images aggressively. For text-heavy PDFs the difference is usually under 10%.
Can I compress a confidential document on StuHub?
Yes — that is exactly the scenario we built for. Because the file never leaves your browser, you can compress contracts, tax forms, or legal documents without them crossing a third-party server.
Does StuHub have the other Smallpdf tools?
Not yet. We have merge, split, rotate, remove pages, extract pages, watermark, metadata editor, PDF→JPG, and Image→PDF. Signatures and OCR are on the roadmap.
