Frequently asked questions
Everything you need to know about compressing images with our free online tool.
- Is this image compressor really free?
- Yes. The Image Compressor is free to use with no signup. We may add a paid tier later for bulk processing and higher upload limits, but the core compressor will always stay free.
- Does it work on JPG, PNG and WebP files?
- Yes. You can compress JPG (.jpg / .jpeg), PNG (.png) and WebP (.webp) images. The output keeps the same format as the input. HEIC, AVIF and animated GIFs are not supported in this version.
- Are my images uploaded to a server?
- No. Compression runs entirely in your web browser using a Web Worker. Your image data never leaves your device, which makes the tool faster and far more private than tools that upload files for processing.
- How much will the file size be reduced?
- Most JPG and PNG images shrink by 60–80% with no visible loss of quality. WebP files are already efficient, so the saving is typically smaller. The exact reduction depends on the original file's compression and dimensions.
- Will compression reduce image quality?
- Slightly, by design — that's how file size goes down. We use defaults tuned for the web: a target around 1MB and a maximum dimension of 1920 pixels on the longest edge. For most use cases — websites, blogs, social media — the result looks visually identical to the original.
- Is there a maximum file size or resolution?
- Single uploads are capped at 25MB to keep the tool responsive in the browser. Output targets around 1MB by default. Images are resized so the longest edge is at most 1920 pixels — perfect for web use, including Retina displays.
- Does it work on my phone?
- Yes. Image Compressor is fully mobile-responsive and works in modern mobile browsers including Safari on iOS and Chrome on Android. You can upload directly from your camera roll.
- Can I compress multiple images at once?
- Bulk image compression is coming soon. For now, you can compress images one at a time. If you'd like early access to bulk mode, keep an eye on the homepage.
- Do compressed images keep their EXIF data?
- No. Re-encoding the image strips most EXIF metadata, including camera info and GPS location. This is generally desirable for images you publish online — it reduces file size further and protects your privacy.
- Is the tool free to use commercially?
- Yes. You can use Image Compressor for personal, commercial, or client work. The compressed files belong to you.
Bulk image compression
