About Image Compressor
Image Compressor is a free browser-based toolkit for compressing, resizing, converting and cropping images. We built it because most online image tools either lock the useful settings behind a paywall, mangle the output with one-size-fits-all defaults, or quietly upload your files to a server you have no relationship with.
Our pitch is simple: a fast, opinionated set of image tools for people who care about how their work looks. Free, private, and with the controls you actually want.
Who it's for
The tools are built first for the people who handle images professionally. Photographers prepping shoots for the web. Designers exporting hero images for client sites. Marketers turning a flood of social assets into something a CMS will actually accept. Developers cleaning up a media library before launch.
That said, none of the workflow assumes you're an expert. If you just need a single phone photo made smaller for email, the defaults handle that in two clicks.
What's in the kit
Five tools, all free, all browser-based:
- Compress with a real quality slider and live before/after preview
- Resize to exact pixels, percentages, or common social media sizes
- Convert between JPG, PNG and WebP
- Crop with aspect-ratio presets, draggable bounds
- Bulk compress a folder of images and download the lot as a single zip
Why browser-based matters
The processing happens in your browser, on your device. Your files are not uploaded to our servers, copied to ours, or held by us in any form. That is true regardless of plan or feature, because there is no upload pipeline in the first place.
A few reasons that matters in practice. If you work with client material under NDA, the files never touch infrastructure you do not control. If you compress something you would rather not have indexed (a contract, an ID photo, a draft poster), it stays local. And because there is no server cost on our side, the tools can stay free forever.
What we do not do
A few things we have deliberately avoided. No accounts, ever. No watermarks. No "you have used 3 of 5 free compressions today" countdowns. No upsell modals in the middle of a session. No automatic upload of your files to a "cloud library" you never asked for.
What we are working on
Bulk image compression is the most recent addition. Next on the list: dedicated EXIF metadata viewing and stripping, batch renaming, and a few more format-specific conversion pages. If you have something you want and we have not built it, please tell us via the contact page.
How the site is funded
Display advertising. That is what keeps the tools free and lets us continue working on them. We are deliberate about ad placement: nothing inside the tools themselves, nothing covering content, no popups. For more on cookies and tracking see our privacy policy.
