Introducing No Bloat PDF: a viewer that just opens

I built No Bloat PDF for a simple reason: I grew to hate opening Adobe PDFs. The most common file on a computer had somehow ended up behind slow launchers, ads, cloud upsells, and sign-in prompts. And everyone I talked to (in every kind of role, working day to day) was quietly putting up with the same thing.

So I built the viewer I wanted. Today it's live, it's free, and you can download it here.

What it is

• Small. The entire installer is 4.6 MB. Not the download stub. The whole thing.
• Instant. Double-click a PDF and you're reading. No launcher, no splash screen, no sync.
• Private. It makes zero network calls. No telemetry, no accounts, no cloud. It can't phone home because there's no home to phone.
• Complete. Tabs for multiple documents, full text search, thumbnails, bookmarks, dark mode, high-resolution printing, highlighting and annotations. The tools you actually use.

Under the hood it pairs Mozilla's pdf.js, the same battle-tested renderer inside Firefox, with a tiny native shell. Proven rendering, none of the weight.

The quiet tools in the sidebar

A viewer earns its keep in the small moments, so I spent most of the build time on the tools you reach for mid-document:

• Page organizing. Delete, reorder, copy, or export pages straight from the thumbnails. The cover page of a scan you never wanted? Gone in two clicks.
• Signatures. Sign a document yourself and place the signature where it belongs. No subscription gate on your own name.
• Sanitize Document. One click strips the metadata out of a file — author names, edit history, the hidden residue — before you send it anywhere.
• Locked files. Password-protected PDFs open like any other. Type the password, read the document, done.

None of these get a splash screen or a price tag. They just sit in the sidebar, fast, the way the rest of the app does.

What it isn't

It's not an editor, and that's deliberate. PDF editing is a swamp of incremental updates, form state, and signature invalidation, the exact swamp that made the big readers slow in the first place. No Bloat PDF does one job at full speed.

What's next

A macOS build is on the roadmap, along with signed installers. Follow this blog or check NoBloatPDF.com for new versions.

Why the code is open

I'm asking you to believe a stranger's promise about zero telemetry, and "trust me" is exactly what the big readers taught everyone to stop accepting. So the whole thing is MIT-licensed open source. You don't have to take my word that it makes no network calls — the code is the proof, and anyone can read it, audit it, or build it themselves. Free software you can verify beats free software you have to hope about.

I'm giving it away because so many people deal with the same problems. No agenda. Nothing to sell.
