Your Images Never Leave Your Browser: How FixMyFoto Protects Your Privacy
Every time you upload a photo to an online image tool, you are trusting a stranger with your files. Most image compression, conversion, and resizing tools quietly upload your photos to a remote server, process them on someone else's computer, and then send the result back. Your images sit on that server for minutes, hours, or sometimes indefinitely. You have no idea who can access them, how long they are stored, or whether they are used to train machine learning models.
FixMyFoto works differently. Every single tool on this site processes your images entirely inside your web browser using JavaScript and the HTML5 Canvas API. Your photos never leave your device. There is no upload, no server, no cloud processing, and no third party storage. When you close the tab, everything is gone.
How Client Side Image Processing Works
When you drop an image into any FixMyFoto tool, the browser reads the file directly from your local filesystem using the JavaScript File API. The image is loaded into an HTML5 Canvas element, which gives the browser access to every pixel. All transformations, whether compression, format conversion, resizing, cropping, rotation, or watermarking, happen as mathematical operations on that pixel data right inside your browser.
The result is written back into a new file using canvas.toBlob(), which creates a downloadable image that exists only in your browser's memory. When you click the download button, the file transfers directly from the browser's memory to your downloads folder. No network request is made. No data crosses the internet. The entire pipeline from input to output stays on your machine.
You can verify this yourself. Open your browser's developer tools, go to the Network tab, and watch while you process an image. You will see zero outgoing requests containing image data. The only network activity is the initial page load.
Why This Matters For Real People
Think about the images you actually need to edit. Product photos for your ecommerce store that you have not listed yet. Client deliverables covered by an NDA. Personal photos you would never want leaked. Medical images or legal documents scanned as photos. ID photos for passport applications. Every one of these carries real risk if uploaded to some random server.
Many popular "free" image tools fund themselves by processing your uploads on their servers, where operational logs, temporary storage, and potential data breaches create a chain of custody you cannot control. Even tools that claim to delete your images after processing cannot guarantee that server logs, CDN caches, or backup systems do not retain copies.
With client side processing, the chain of custody is zero links long. Your file never touches a network socket. There is nothing to delete because nothing was ever stored.
No Account Required, No Tracking of Your Files
FixMyFoto does not require you to create an account, verify an email, or hand over any personal information to use the tools. There is no login wall. There is no "sign up to download your result" gate. You open the page, drop your image, get your result, and move on.
The site uses Google Analytics to understand general traffic patterns like page views and referral sources. It does not track which images you process, what file names you use, or any content of your files. This is structurally impossible because your files never reach any server in the first place.
Works Offline Too
Because all processing is local, FixMyFoto tools continue to work even if your internet connection drops after the page loads. You can load the page, disconnect from wifi, and still compress, convert, resize, crop, rotate, and watermark images. Try that with a server based tool.
Open and Verifiable
Every tool on FixMyFoto is built with standard web technologies. The JavaScript source code is visible in your browser. There are no obfuscated binaries, no WebAssembly blobs hiding server calls, and no hidden iframes phoning home. You can inspect exactly what the code does using your browser's view source feature.
This transparency is a feature, not a limitation. When privacy is the product, auditability is the proof.
Bottom line: Your images are your business. FixMyFoto gives you professional grade image tools with zero privacy compromises. No uploads, no accounts, no server processing, and no trust required.
