Announcing qpdf-rs: Rust bindings to C++ QPDF library for PDF manipulations
The project aims to create a safe wrapper over a popular QPDF library using it's C API bindings. It's still in development but I think is already usable. Not published yet on crates.io, some work is still missing on documentation, general polish and API stabilization. Use cases: PDF transformations such as page extraction/deletion/duplication, page rotation, booklets/N-up formatting, merging of documents, PDF decryption, etc.

Ask HN: How to handle user file uploads?
Read through the comments and was surprised no one mentioned libvips - https://github.com/libvips/libvips. At my current small company we were trying to allow image uploads and started with imagemagick but certain images took too long to process and we were looking for faster alternatives. It's a great tool with minimum overhead. For video thumbnails, we use ffmpeg which is really heavy. We off-load video thumbnail generation to a queue. We've had great luck with these tools.

.Webp is the bane of my existence
if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.
