A fresh set every week
The flagship studio plus six picks that rotate every week. Each opens instantly on its own page.
Three steps. Zero friction.
From file to finished in moments — that's the whole idea behind the Studio.
- Step 01
Pick your tool
Search or browse 80 tools across 13 categories. Every tool opens on its own fast page — no installs, no sign-up.
- Step 02
Watch it transform
Drop your file in and see real progress as it converts, merges, compresses or edits — right in your browser whenever the tool is local.
- Step 03
Download & go
Your finished file, verified and ready. No watermark, no email gate, nothing kept on a server for local tools.
Every PDF job, done in the browser
Merge, split, compress, convert, sign, rotate and edit PDFs — the flagship Live PDF Studio included. Files stay on your device.
Compress, convert, resize and read images
JPG, PNG, WebP and HEIC converters, an image compressor, resizer, background remover and OCR — plus everyday unit converters.

Private, fast and honest by design
What you can actually expect every time you open a ByteXpresso tool.
Private by default
Files you open in local tools never leave your device. We don't store what you process.
Local processing where possible
PDF, image, text, developer, calculator and OCR tools run right in your browser.
No API keys, no cloud AI
Every tool works without an account or API key, and every card says where your file is processed.
No sign-up
Open a tool and start. No account, no email, no watermark on your results.
Fast in the browser
Each tool loads on its own page, and heavy engines load only when you use them.
Built for phones too
Designed to work on small phones as well as wide desktops.
Questions people ask before their first tool run
Are all ByteXpresso tools free to use?
Yes. All 80 tools are free with no account, no trial and no watermark on your results. The studio is partly supported by clearly labelled partner recommendations, which never changes what a tool does or costs you.
Are my files uploaded to a server?
No — all 80 tools run entirely inside your browser, so your files never leave your device.
Do I need to create an account or install anything?
No. ByteXpresso runs in any modern browser on desktop, tablet and phone. Open a tool, drop in your file or text, and get the result — there is nothing to install and no sign-up step.
Which file formats can I work with?
PDF tools cover merging, splitting, compressing, converting to Word, Excel and PowerPoint, signing, rotating, cropping and more. Image tools handle JPG, PNG, WebP and HEIC for compressing, resizing, converting, cropping and OCR. There are also text, developer, calculator, QR and security tools.
What is the PDF Live Studio?
It is the flagship editor: organize pages, add text, drawings, highlights, shapes, images, links and signatures, white-out content, then export a real PDF — all rendered live in your browser with an undo history.
