Video instructions showing how to open and extract SFX files online.
- To select the SFX file, you have two options:
- Click "Select SFX file to open" to open the file chooser
- Drag and drop the SFX file directly onto ezyZip
Click "Select SFX file to open" to open the file chooser
It will start the file extraction and list the contents of the SFX file once complete. - Click the green "Save" button on the individual files to save to your selected destination folder.
- OPTIONAL: Click "Preview" to open directly in the browser. Click "Share" to send via e-mail, messenger, or other services. These options are only available for some file types.
Some newer browsers allow the saving of multiple files & folders into a designated target folder in one go. If you wish to extract all files in the SFX file and maintain existing folder structure, follow the steps the below:
- Follow the above instructions to open SFX file
- Click on "Save All". If the button is disabled, it means your browser does not support this feature or it is not enabled.
- Select an empty folder where you wish to extract the files. Please note: If you already have files with the same name, ezyZip WILL OVERWRITE THEM.
- After you have selected the folder, the browser will ask for permission to access it. Click on "View files" followed by "Save changes".
- It will then commence saving files and subfolders into the target you specified
If you want to see what's inside the SFX file without having to extract all the files first, follow the steps below:
- Open the SFX file, as per instructions above. It will initially list the contents of the SFX hierarchically, sorted by folders.
- Click on "List all files" to see the entire list of files inside the archive.
- Click on "List by folder" to go back to folder view.
To extract just a subfolder and all its contents:
Please note: This feature is currently only available on supported browsers like Chrome and Edge.
- Follow the above instructions to open SFX file
- Navigate to the parent folder within the SFX file
- Click the "Save" button on the row of the subfolder you want to extract
- All files and folders from that subfolder will be saved to your chosen destination.
Please note: This feature is currently only available on supported browsers like Chrome and Edge.
- Click on the Dropbox logo () in the SFX file selector button.
- The Dropbox file chooser will appear. You will need to authorise access to ezyZip the first time.
- Once you have selected the SFX file, it will download it to your browser and show the contents.
- To save files to Dropbox, click on "Dropbox" dropdown under the "Save" or "Save All" buttons. You will need to authorise Dropbox for ezyZip the first time you do it.
Files will be saved in /Apps/ezyZip folder.
Yes, ezyZip offers a specialized archive content previewer feature that allows you to view the contents of certain types of files within your SFX files without needing to extract them. This feature supports a range of file types, including images, audio, video, and documents, providing a quick and convenient way to verify or check the contents of these files within your archives. Simply click on the blue "Preview" button.
Yes. ezyZip utilises the processing power of your own computer and browser to complete the task. No file data leaves your browser. Unsure? Turn off your WiFi when completing the uncompression. It will continue to work as no data is uploaded to the internet.

An SFX file (Self-Extracting archive) is an executable file that contains compressed data along with built-in extraction code. Unlike standard archive formats, SFX files do not require any decompression software to be installed on the recipient's computer — the user simply runs the file and the contents are automatically extracted.
SFX archives are commonly created from ZIP, RAR, or 7Z archives and are widely used for distributing compressed files to users who may not have archive utilities installed. ezyZip uses the 7-Zip format to generate its SFX archives, producing .exe files that will self-extract on Windows platforms. ezyZip can also safely extract the contents of SFX files directly in your browser without needing to run the executable, avoiding potential security risks.
ezyZip processes files directly in your browser. Unlike most online tools, your files are not uploaded to our servers, which means faster processing and better privacy. Take a look at the feature comparison below and we think youll agree that ezyZip is the better choice for your file conversion needs.

Why client-side SFX extraction is faster than server-based tools
ezyZip processes SFX archives locally using client-side WebAssembly (WASM). Here is why our engine is superior to server-based extractors:
- No Upload/Download DelaysYour extraction speed is limited only by your local CPU and disk I/O, not your internet connection. A 2 GB archive that takes 20 minutes to upload on a typical connection extracts in seconds locally.
- Multi-Engine FailoverIf one decompression engine encounters a rare error, ezyZip automatically switches to an alternative extractor. This cascading approach supports over 130 archive formats and handles edge cases like non-standard headers or mixed-method compression.
- Large File SupportBy leveraging the File System Access API and Origin Private File System (OPFS), ezyZip streams data directly to your disk, avoiding the memory crashes common in other browser-based tools. Archives of virtually any size can be extracted without exhausting RAM.
- Dedicated Worker ThreadsExtraction runs in dedicated Web Workers on separate threads, keeping the browser interface fully responsive. You can monitor per-file progress, preview extracted files, and continue browsing while decompression runs in the background.
- Advanced Memory HandlingFor massive archives, our Memory64 WebAssembly build bypasses standard browser memory limits, allowing you to extract files that would crash other sites. This extended addressing mode supports archives well beyond the typical 4 GB WASM memory ceiling.
