iLovePDF, SmallPDF, and TinyPNG are the names most people reach for first with a PDF or image file-size problem, mostly because they rank well - not necessarily because they're the only option. A lot of their core features (the ones most people actually use) have straightforward free equivalents.

For PDF compression, merging, and splitting

Our Compress PDF shrinks a file down to a target size, Merge PDF combines multiple files into one, and Organize PDF handles rearranging and managing pages within a document - all without a watermark, a daily usage cap, or a nag screen pushing a paid plan.

For PDF conversion

PDF to Word, PDF to JPG, Image to PDF, and Word to PDF cover the conversions people reach for most often between these two formats.

For password protection

Protect PDF adds a password to a sensitive document, and Unlock PDF removes one you've already set and no longer need.

For image compression (the TinyPNG use case)

Our Image Compressor covers the same core job TinyPNG is known for - shrinking JPG, PNG, and WEBP files down - with a live slider so you can see the resulting file size and quality trade-off before you commit, rather than getting a fixed, non-adjustable compression level.

Why it's worth trying the alternative

All of the tools above run entirely in your browser rather than requiring an account, so there's no file-count limit tied to a free tier and nothing is stored on a server afterward - worth knowing if you're dealing with a sensitive document and would rather it never left your device in the first place.
