imageAbout BMP Compressor
BMP Compressor is built for image editing and conversion jobs that fit cleanly into a browser tab. Upload a BMP image and compress it by converting to PNG, JPEG, or WebP with adjustable quality. The processing runs in the page itself, which is why the controls update instantly when you change settings and why a freshly loaded page is ready to do real work the moment it becomes interactive.
If you fit any of these descriptions, BMP Compressor should slot cleanly into your workflow: illustrators packaging artwork; social-media managers sizing posts; students compiling visual reports. The tool keeps the controls focused on what matters for each of these use cases.
BMP Compressor runs the entire transformation inside your browser. The file is read by JavaScript running in the page, processed in-memory by standard browser APIs, and written back as a download. The browser is the runtime; the page is the interface. You can confirm what the tool does by opening the developer-tools Network tab during a run — the only requests are for the page's own static assets.
Architecturally, BMP Compressor is a single-page client. The processing layer is standard browser APIs; the UI is a thin React shell on top. PNG, JPG, GIF, WebP, BMP, and SVG inputs flow through the engine and the output is returned to the browser as a Blob you can save or copy. The 100 MB cap is the only hard limit and it exists to keep memory usage stable on every device.
BMP Compressor works well as a bookmarked utility you reach for when you need it. The first visit shows you what the tool does; the second is when you realise it is a low-friction option for the task and worth keeping in your tab list.
As a workflow component, BMP Compressor is the part you reach for when a single, well-defined image editing and conversion step needs to happen. It performs that step and returns a standard file you can carry into the next part of your pipeline.
BMP Compressor returns the result as a download. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
The architecture imposes only the limits the browser itself imposes. The published 100 MB ceiling is conservative; most modern devices comfortably handle inputs up to that size, and the cap exists so the tool degrades gracefully on phones and budget laptops rather than running out of memory.
BMP Compressor is honest about scope: it handles a single, well-defined image editing and conversion step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.
A short note on how BMP Compressor came to look the way it does: every iteration started by watching how someone unfamiliar with the tool actually used it, then removing whatever got in their way. That is why the upload area dominates the screen, the run button is bigger than the secondary controls, and the result panel is unmissable when the job finishes.
Tips from users who reach for BMP Compressor regularly: process one input first to confirm the settings produce what you expect before committing to a batch; treat the page as the working surface and avoid leaving large jobs running in a backgrounded tab where the browser may throttle JavaScript; and if a particular file fails, check whether the source is intact by opening it in its native viewer — most "tool errors" are actually input errors.
Common gotchas worth flagging: BMP Compressor only accepts PNG, JPG, GIF, WebP, BMP, and SVG, so if your file is in another format you will need to convert it first. The 100 MB ceiling is per-file, not per-session; you can run as many separate jobs as you like, but a single oversized input will be rejected on load.
BMP Compressor produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
BMP Compressor is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Reach the BMP Compressor page in your browser to begin.
- 2Select the PNG, JPG, GIF, WebP, BMP, and SVG file you want to process — drag-and-drop and the file picker both work.
- 3Pick any non-default settings you need. Most users leave the defaults alone for the first run and only revisit if the result needs tuning.
- 4Click to start the job. The engine (standard browser APIs) processes the input in the page; you can watch the progress indicator until it completes.
- 5Save the output when it is ready.
- 6Re-run with different settings as often as you want. Each run produces a fresh output and the original file on disk is never modified.

FAQ
How much compression?
BMP files are uncompressed — expect 70-95% size reduction when converting to PNG or JPEG.
PNG or JPEG?
PNG for lossless quality; JPEG for maximum compression with slight quality loss.
Quality control?
JPEG quality is adjustable from 1-100%; PNG is always lossless.
Is my data safe?
All compression happens in your browser — no files are uploaded.
Transparency?
PNG preserves transparency; JPEG does not support it.
Color depth?
Both output formats support full 24-bit color from BMP sources.
Can I use BMP Compressor on iOS or Android?
BMP Compressor runs in any modern mobile browser — Safari, Chrome, Firefox and the in-app browsers in most messaging apps all support the underlying APIs. Performance depends on the device: a recent phone handles typical inputs nearly as fast as a laptop, while older devices may take a few seconds longer near the 100 MB ceiling. The interface lays out cleanly on small screens, so you do not need to pinch-zoom to see the controls.
Can I trust the output of BMP Compressor for important work?
BMP Compressor is built on standard browser APIs, which is the same class of engine used by professional image editing and conversion pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
Which file formats does BMP Compressor accept?
BMP Compressor accepts PNG, JPG, GIF, WebP, BMP, and SVG. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
Do I need a specific browser to use BMP Compressor?
BMP Compressor works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
Is BMP Compressor lossless?
BMP Compressor is built to preserve quality wherever the underlying image format allows it. Operations that are mathematically lossless (e.g. structural transformations, lossless re-encoding) round-trip with no perceptible change. Operations that involve a lossy codec inevitably introduce small artefacts at the byte level, but the defaults aim at the sweet spot where output looks or sounds the same to a normal viewer or listener while still being meaningfully smaller or faster than the input.
Why did BMP Compressor reject my input?
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is one of PNG, JPG, GIF, WebP, BMP, and SVG and that it is below 100 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
How long does Favtoo retain my data after using BMP Compressor?
Favtoo keeps no copy of your file because Favtoo never receives your file. BMP Compressor runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
