Frequently Asked Questions
What image formats can I compress?
Our compressor supports all major image formats: JPG, JPEG, PNG, WebP, HEIC (iPhone), HEIF, AVIF, SVG, GIF, TIFF, BMP, and more. Just drag and drop any image type.
Does compressing an image reduce its quality?
Compression always involves a trade-off. At 80–90% quality, most people cannot see any visible difference in photos. The quality slider lets you find the perfect balance between file size and sharpness for your use case.
Is my image uploaded to a server?
No. All compression happens 100% in your browser using the HTML5 Canvas API. Your images are never sent to any server, ensuring complete privacy. Files stay on your device at all times.
Can I resize and compress at the same time?
Yes! Enter a target width and/or height in the resize fields, enable aspect ratio lock to prevent distortion, and compress. Both operations are applied simultaneously in one step.
What output formats can I download?
You can download your compressed images as JPG (best for photos), PNG (best for graphics with transparency), or WebP (best for web performance and smaller sizes).
How many images can I compress at once?
There is no hard limit. You can compress dozens of images in a single batch. Each file can be up to 50 MB. The entire batch is processed simultaneously in your browser.
Why should I compress images for my website?
Oversized images are one of the biggest causes of slow websites. Compressed images load faster, reducing bounce rates, improving Google Core Web Vitals, and boosting SEO rankings — all without affecting the visual experience.
