What Is Image Compression?
Image compression reduces the file size of JPG, PNG and WebP images. It helps with faster website loading, email attachment size limits and saving storage space, anywhere you work with images.
SOKUFU's image compressor does all of the work in your browser. Your images are never sent to a server, so you can safely compress internal documents and personal photos. You can also compress several files at once.
Choose a compression strength to balance quality and file size, whether you are optimizing images for the web, lightening photos for social media or shrinking files for email. No sign-up, no login and no usage limits.

Image Compressor FAQ
- Are my files uploaded to a server?
- No. All processing is done in your browser, and your image files are never sent to any external server. You can safely use this tool even with images containing personal information.
- What image formats are supported?
- JPEG, PNG, WebP, GIF, BMP and HEIC (iPhone photos) are supported. You can also convert to WebP or JPEG during compression.
- How much compression can I expect?
- It depends on the image type and content. After compressing, the tool shows how much smaller each image became and the total saving.
- What happens to the image quality after compression?
- There are three strengths. "Light (best quality)" keeps almost all of the quality and leaves the dimensions unchanged. "Standard" reduces file size with little visible change and scales images whose long side is over 2048px down to 2048px. "Strong (smallest file)" reduces file size a lot and scales images whose long side is over 1280px down to 1280px.
- How many files can I compress at once?
- Select as many as you need and compress them in one go. There is no fixed cap on how many files or how large they are; it depends on your device's memory. No sign-up is needed and there is no daily limit.
- What is Exif data?
- Exif data is metadata embedded in photos, such as the date taken, camera model and GPS coordinates.
- What happens if I remove Exif data?
- The file gets a little smaller, and your location and other personal details are not exposed when you share the image online. It has no effect on how the image looks.
- Can I compress to a specific file size?
- Yes. Choose "By target size" and pick 100 KB, 200 KB, 500 KB or 1000 KB. Quality is adjusted automatically so each image ends up at or below that size, which is handy for email or upload limits.
- How does this compare to TinyPNG?
- SOKUFU processes files entirely in your browser, so nothing is uploaded to a server. It also reads HEIC files and supports format conversion, Exif removal and target file size mode.
- How do I get a photo under 100 KB for an online form?
- Choose "By target size", set it to 100 KB and compress. The tool lowers quality step by step until the file fits. If the result looks too soft, shrink the image with the Image Resizer first, then compress again.
- Can I compress iPhone HEIC photos?
- Yes. HEIC files are read directly, and you can save them as JPEG for the widest compatibility or WebP for the smallest size.
- Does compressing remove the location from my photo?
- Yes, when "Remove photo data (Exif)" is on, which it is by default. GPS coordinates, the date taken and camera details are then stripped from the saved file.
