Our Mission

Why We Built JPG2Go

Most online image converters make you upload your files to a remote server, wait in a queue, and trust that a third party handles your data responsibly. We built JPG2Go because that trade-off was unnecessary. Modern browsers are powerful enough to convert images locally, instantly, and privately — without a server ever being involved.

JPG2Go runs entirely inside your browser using the HTML5 Canvas API. When you select an image, it never leaves your device. There are no upload queues, no cloud storage, no analytics tied to your files, and no premium tier designed to lock away basic features. Every conversion, every format, every quality setting — free, forever.

We believe a useful tool should respect the people who use it. That means no sign-up friction, no file-size paywalls, and no advertising built on tracking your behaviour. Just a fast, honest image converter that does exactly what it says.

Privacy First

Your Images Never Leave Your Device

Most tools treat your files as data to be processed on someone else's infrastructure. JPG2Go is architecturally different. Here is exactly how your privacy is protected at every step.

No Server, No Upload
JPG2Go has no backend upload endpoint. When you select a file, it is read locally by your browser's File API. No HTTP request containing your image data is ever made.
Instant Client-Side Processing
Conversion runs synchronously in your browser using the HTML5 Canvas API. The output file is generated in memory and handed directly to your browser's download handler.
No File Logging
We do not log filenames, file sizes, image metadata, or conversion activity. Standard server access logs only record page requests, not tool usage.
No Account Required
There is no sign-up, login, or email collection. Anonymous use is the only mode. There is no user profile to breach, because there is no user profile at all.
No Tracking Pixels or Ad SDKs
JPG2Go loads no third-party advertising scripts, retargeting pixels, or behavioural analytics SDKs. The only external resource loaded is Google Fonts for typography.
Works Offline After First Load
Because all conversion logic is self-contained JavaScript, JPG2Go continues to work in degraded network conditions or offline once the page has been loaded initially.
Technology

How JPG2Go Works Under the Hood

JPG2Go is a zero-dependency, single-page application built entirely on Web Platform APIs. No Node.js server, no image processing library, no WebAssembly binary — just standard browser APIs that have been available in every major browser since 2018.

Input
File API & Drag-and-Drop API
Images are read from the user's filesystem using the browser's native File API. Drag-and-drop is handled via the DataTransfer interface. No temporary copies are written anywhere outside browser memory.
Preview
Object URLs & HTMLImageElement
Thumbnails are generated by creating a temporary Blob URL with URL.createObjectURL(). These URLs are revoked immediately after the image is loaded to prevent memory leaks.
Conversion
HTML5 Canvas API
Each image is drawn onto an off-screen canvas element at its native dimensions. HTMLCanvasElement.toBlob() then re-encodes the pixel data into the chosen output format using the browser's built-in codecs.
Quality
Codec Quality Parameter
For lossy formats (JPG, WebP, AVIF), the quality slider maps to the encoderOptions argument passed to toBlob(). Lossless formats (PNG, GIF, BMP) ignore this parameter and always encode at maximum fidelity.
Output
Programmatic Download
Converted Blobs are turned back into Object URLs and attached to a dynamically created anchor element. Calling .click() on it triggers the browser's standard Save dialog, handing the file to the OS with the correct extension.
Batch
Sequential Async Processing
Multiple files are processed in sequence using async/await to avoid UI blocking. Each file updates its own progress indicator as it completes, giving real-time visual feedback during batch conversions.
Our Values

The Principles Behind Every Decision

Every feature added, every line of code written, and every design choice made for JPG2Go is measured against these four principles.

01
Privacy is not a feature — it is the architecture
We do not treat privacy as a marketing checkbox or a premium add-on. The decision to process everything client-side was made at the design stage, not bolted on afterwards. If a future feature would require uploading user files to a server, we will not build that feature.
02
Speed is a form of respect
When you need to convert an image, you do not want to wait for a server round-trip, a queue, or a progress spinner that drags on for seconds. Local processing is faster than any server-side alternative. Instant results respect your time.
03
Free means free — no asterisks
JPG2Go has no file-size limit, no daily conversion cap, no watermark on output, and no features gated behind a paid tier. The complete tool is free because limiting it would make it less useful, and we built it to be as useful as possible.
04
Simplicity scales better than complexity
We deliberately avoid adding features that would complicate the interface without meaningfully improving output quality. Resize, crop, filters, and watermarking are better handled by dedicated tools. JPG2Go does one thing — format conversion — and does it well.
