What is an image compressor?

An image compressor reduces the file size of photos and graphics by removing redundant data or re-encoding pixels more efficiently. ImageCompressor.net lets you compress JPG, PNG, WebP, and GIF files online for free, directly in your browser.

Can I compress images without losing quality?

Yes. Use lossless compression mode to preserve every pixel while still reducing file size. For photos, lossy mode at 75–85% quality typically produces files 50–80% smaller with no visible difference.

Is ImageCompressor.net free?

Yes. Compressing images is completely free with no file limit, no watermark, and no feature locked behind a paywall or subscription.

Do you store my images?

No. Compression runs locally in your browser using the Canvas API. Your images are never uploaded to our servers, logged, or stored anywhere.

How much can I reduce image size?

Typical photos shrink by 50–80% with no visible quality loss. PNG graphics and screenshots often see 30–60% reduction. Results vary based on image content and compression settings.

Can I compress multiple images at once?

Yes. Batch upload lets you drop dozens of files and compress them together with the same settings. Download each file individually or grab the entire batch as a ZIP archive.

Does it support WebP compression?

Yes. You can compress WebP files and convert JPG or PNG images to WebP for even smaller file sizes with broad modern browser support.

Can I convert PNG to JPG?

Yes. Select JPG as the output format before compressing. This removes transparency but significantly reduces file size for photos and screenshots.

What's the difference between lossy and lossless compression?

Lossy compression discards imperceptible detail to achieve much smaller files — ideal for photos. Lossless compression preserves every pixel exactly — best for logos, screenshots and graphics with sharp edges.

Is there a file size or count limit?

No artificial limit is applied. Very large batches are only bound by your device's available memory.

Does this tool add a watermark?

Never. Every exported image is the clean, compressed file with nothing added.

Does compressing images help with SEO?

Yes. Smaller images load faster, improving Core Web Vitals like LCP (Largest Contentful Paint). Page speed is a confirmed Google ranking factor, and optimized images are one of the fastest wins for site performance.

Can I use this on my phone?

Yes. The tool works in mobile browsers with touch-friendly drag-and-drop, slider controls, and responsive layout.

Does it work without an internet connection?

Once the page has loaded, core compression keeps working offline since processing happens locally in your browser.

What is target file size mode?

Target file size mode lets you specify a size in kilobytes. The tool searches for the highest quality setting that fits within your limit — perfect for email attachments or CMS upload caps.

Can I compress PNG without losing transparency?

Yes. Use lossless mode with PNG output to preserve the alpha channel while still reducing file size.

What's the best format for a website?

WebP typically produces the smallest files at a given quality. Use WebP for broad compatibility.

How is this different from TinyPNG?

ImageCompressor.net processes files locally in your browser rather than uploading to a server. It adds target file size mode, unlimited batch uploads, live before/after preview, and format conversion.

Can I use this tool commercially?

Yes. Compressed images are yours to use for any personal or commercial purpose with no attribution required.

Does compression change image dimensions?

No. Compression alone does not change width or height unless you separately choose to resize.

Is SVG compression the same as raster compression?

No. SVG files are vector graphics. Raster compression re-encodes pixels; SVG optimization removes redundant markup and whitespace.

Why is my JPG not getting much smaller?

If the image was already heavily compressed or is very small, there is less redundant data left to remove. Try converting to WebP for additional savings.
