Which image formats can be compressed?
The compressor handles JPG, JPEG, PNG and WebP. It reduces file size through two controls: quality percentage and output dimensions. The format is preserved after compression, so results work directly on websites, e-commerce platforms and social media.
How do I compress an image to a target size like 500KB?
Upload the image, then drag the quality slider while watching the live size estimate. Adjust width/height too, since the tool updates the projected file size in real time. Fine-tune until you hit your KB/MB target, then download.
Does online compression noticeably reduce quality?
Compression always involves slight loss, but the 1%-100% quality slider lets you choose the trade-off. Starting at 80% is usually visually indistinguishable for web, chat and document use while cutting file size by half or more.
Is the aspect ratio preserved when compressing?
Yes. The tool locks the aspect ratio by default — changing width scales height automatically to prevent distortion. Unlock it first for custom sizes, useful for uniform e-commerce main images and covers.
Is it safe? Will my image be uploaded?
Safe. All compression runs locally in your browser; images never leave your device. This makes it suitable for photos with personal info, business secrets or copyrighted content.
Is the compressed result good for web and SEO?
Very. Smaller WEBP/JPG files load faster, directly improving Core Web Vitals scores and search rankings. Outputting WEBP and pairing with the resize tool gives a strong mobile experience.
Are there limits on free compression?
No usage limits and no registration. Keep single images under 100MB for smooth processing. The tool suits high-frequency workloads like e-commerce product batches and designer deliveries.
Can I compress animated GIFs?
GIFs are processed as static images (first frame), losing animation. For animated output, regenerate with the video-to-GIF tool using fewer frames and smaller dimensions.
