Frequently Asked Questions
How do I compress images without losing visual quality?
Upload your images, choose your target quality level (e.g. 80% visually lossless), or specify a maximum target file size in KB/MB, and click Compress. The browser optimizes the pixel data and quantization tables locally.
Are my photos uploaded to a remote server for compression?
No. All compression algorithms execute directly in your web browser using WebAssembly and Web Workers. Your personal photos never leave your device.
Which image formats can be compressed?
You can compress JPEG/JPG, PNG, WebP, GIF, and modern AVIF image formats.
Can I compress transparent PNG files without losing transparency?
Yes. Our PNG compression engine optimizes alpha channel palettes losslessly or with perceptually tuned quantization so transparency remains perfectly intact.
Can I batch compress multiple photos at the same time?
Yes. You can drag and drop dozens of photos at once. Each image is compressed in parallel using background worker threads, and you can download them all in a ZIP archive.
What is the difference between lossy and lossless compression?
Lossless compression removes unnecessary metadata and optimizes byte encoding without changing pixel data (10-25% reduction). Lossy compression selectively simplifies invisible color nuances to reduce file size by up to 80-90% with virtually indistinguishable visual difference.
Can I set an exact target file size (e.g. compress image to under 100KB or 50KB)?
Yes. Our smart compressor iterates quality parameters client-side to automatically hit your desired target size threshold for government forms and portal uploads.
Will image metadata (EXIF, GPS, camera model) be stripped for privacy?
Yes, by default EXIF tags, GPS coordinates, and camera timestamps are stripped to protect your privacy and reduce file size, or you can choose to preserve them.
Does the image compressor work on mobile smartphones?
Yes, it works smoothly on iOS Safari and Android Chrome, allowing you to compress photos directly from your camera roll before texting or emailing.
How fast is client-side image compression?
Because photos don't need to be sent across the internet, images are compressed within milliseconds by your device's multi-core CPU.
Does compressing photos add any watermarks?
No. Your output photos are 100% clean with zero watermarks or logos.
Can I use the Image Compressor while offline?
Yes. Once the page is loaded, the compression libraries run offline without requiring any active internet connection.
Is there a limit on how many images I can compress per day?
No. The compressor is completely free with unlimited daily usage and no registration required.
How does in-browser compression compare to desktop tools like TinyPNG or Photoshop?
You get comparable visual optimization results to TinyPNG and Photoshop's Save for Web without paying subscription fees or uploading confidential photos to third-party clouds.
What should I do if my compressed image still looks too large?
Try switching the output format to modern WebP, which generally provides 25-35% better compression efficiency than standard JPEG at equivalent visual quality.
