Why BravoConvert exists
BravoConvert started from a simple frustration: most online image and PDF tools ask you to upload a file to a server before doing something as basic as changing its format or resizing it. That means waiting for an upload, trusting a stranger with the contents of a document, and often creating an account first — for a task your own computer could finish in a second. This site does those everyday jobs entirely inside your browser instead.
What it does
Three tools, each doing one thing: Image Converter for changing formats and batching, PDF Converter for turning document pages into images, and Image Editor for resizing, rotating and flipping a single picture.
- Convert between JPG, PNG and WebP, one file or a batch
- Combine several images into a single PDF document
- Render PDF pages as JPG or PNG images
- Resize a single image, with aspect ratio locking
- Rotate in 90-degree steps and flip horizontally or vertically
- Export edited images as JPG, PNG or WebP
- Set an output quality level, or aim for a target file size
- Download a batch as a ZIP archive
How “in your browser” actually works
When you pick a file, the browser reads it from your disk into memory. Image conversion is handed to a Web Worker so the page stays responsive, where the image is decoded, drawn onto an off-screen canvas, and re-encoded in the format you asked for. PDF pages are rendered to a canvas by PDF.js and captured the same way. The result is handed back as a download.
At no point does the file travel anywhere. There is no upload endpoint to send it to — the site is a set of static files, and the conversion code runs on your machine. A useful side effect: because output is rebuilt from decoded pixels rather than copied from the source file, camera metadata such as GPS coordinates does not survive the conversion. We tested that rather than assuming it.
What it deliberately does not do
A tool is more useful when its limits are stated plainly rather than discovered.
JPG, PNG and WebP for images; PDF for documents. HEIC from an iPhone, RAW files from a camera, TIFF, GIF, BMP and SVG are not accepted. Supporting them properly in a browser means shipping a decoder for each, and a half-working decoder is worse than an honest refusal.
10 MB per image, 50 MB per PDF, and 64 megapixels in the editor. These exist because the file has to fit in your browser's memory — there is no server to hand the work to. Large jobs will fail on a phone before they fail on a desktop.
Pages render at 144 DPI. That is sharp on any display and fine for slides or sharing, but commercial printing wants 300 DPI. For print, send the original PDF.
There are no accounts and no history. Close the tab and the working session is gone. Keep your originals — this is a tool for making copies, not a place to keep files.
How the guides are written
The guides avoid the approximate ratios that get copied between articles. Their numbers come from a script in this project that encodes deterministic test images through the same browser API the converters use, then records the exact byte counts — most recently on 2026-09-02 against Chromium 151.0.7922.34. The test files are published for download so anyone can reproduce the results, and where the measurements contradicted received wisdom, the guides say so rather than repeating the received wisdom.
Who runs it, and how it is paid for
BravoConvert is an independently operated site, not a company product. The tools are free to use, there is nothing to sign up for, and there is no paid tier.
Running costs are covered by advertising. That is the only revenue involved: the site does not sell data, and the contents of the files you convert are never transmitted anywhere, so there is nothing about them to sell. What advertising does mean is that Google's advertising and analytics tags load on these pages, and the privacy policy sets out exactly what they may and may not do before and after you make a choice in the consent panel.
Corrections welcome
If something here is wrong, or a guide claims a behaviour the site does not actually have, that is worth knowing — several claims have already been corrected after being checked against the code. Email bravoconvert.help@gmail.com and say what you saw.
What is next
The Image Editor currently covers resize, rotate and flip. Free-form cropping, batch editing and additional input formats are under consideration, and will only ship once they work reliably in a browser rather than approximately. The changelog records what has actually shipped, not what is planned.
Elsewhere on the site
The usage guide walks through each tool step by step, the FAQ answers the questions that come up most, and troubleshooting covers what to do when something fails. For anything else, get in touch.
