Image Compressor

Image compression is the process of reducing the file size of an image by removing redundant data or using more efficient encoding. This makes images faster to upload, download, and display — while preserving visual quality.

Image compression works by either removing unnecessary data (lossy) or finding more efficient ways to store the same data (lossless). Our tool uses the Canvas API to re-encode images in your browser with your chosen quality level.

It depends on the compression level. Light compression (80–100%) produces nearly lossless results. Balanced compression (60–80%) has acceptable quality for most uses. Maximum compression (below 50%) shows visible quality loss. You control this with the quality slider and can preview before downloading.

Yes, our image compressor is completely free with no signup, no watermarks, and no limits on the number of images you can compress.

Yes. There are no limits on how many images you can compress. Use batch mode to compress dozens of images at once and download them all as a ZIP file.

AVIF offers the best compression ratios (up to 50% smaller than JPEG at the same quality). WebP is the best balance of compression and browser support. JPEG remains the most universally compatible format.

Lossy compression permanently removes some image data to achieve smaller file sizes — the quality loss is irreversible. Lossless compression reduces file size without removing any information — the original quality can be fully restored.

Typical reductions range from 40% to 90% depending on the image content, format, and quality setting. WebP and AVIF formats achieve the best compression ratios. A 5MB photo can often be compressed to 200–500KB at 75% quality.

Not unless you enable the resize option. By default, compression preserves the original dimensions. You can optionally set a max width/height to resize during compression.

EXIF/GPS metadata removal is optional. When enabled, it strips camera information, GPS coordinates, and timestamps — protecting your privacy. When disabled, metadata is preserved.

Yes. Our tool preserves transparency when compressing PNG images. The alpha channel is maintained, so your transparent backgrounds stay intact.

Yes. WebP is fully supported as both input and output format. You can compress existing WebP files or convert from any other format to WebP for better compression.

Set the quality slider to 15–30%, enable resize and set max dimensions to around 300x300px, and choose JPEG as the output format. Preview the result and adjust until you hit the target size.

Set the quality slider to 25–40%, optionally resize to 500x500px, and use JPEG output. For passport or visa photos, resize to the required dimensions (e.g., 350x450px) and adjust quality to hit 50KB.

Set quality to 50–70% for JPEG output. If the image is large, resize to 800x800px or smaller. This quality range provides a good balance of readability and file size reduction.

Set quality to 70–80% for JPEG output. Most website images and social media photos work well at this level. Use WebP format for even better results at the same quality.

Most images can be compressed under 1MB at 60–80% quality without noticeable quality loss. For large photos (5MB+), set quality to 65–75% and use JPEG or WebP output.

No. Your images are never uploaded to any server. All compression happens locally in your browser using the Canvas API. Your data never leaves your device.

Since images are never uploaded to a server, there is nothing to delete. The compressed image is generated entirely in your browser. Close the tab and the data is gone.

Yes, our image compression is completely safe. All processing is client-side — your images never leave your device. No data is collected, stored, or transmitted.

Yes. Compressing images for websites improves page load speed, reduces bandwidth usage, and boosts SEO rankings. Use WebP format at 75–85% quality for the best balance of quality and performance.

Yes. Large photos often exceed email attachment limits (typically 10–25MB). Compress images to under 1MB for easy emailing while maintaining good visual quality.

Yes. Government portals (passport, visa, tax filing, voter registration) typically require images under 50KB–200KB. Use our tool to compress to the exact size limit with the resize option.

The best image compressor is one that supports all formats, offers quality control, runs privately in your browser, and provides before/after previews. Our tool offers all of these features with batch processing, format conversion, and metadata removal — completely free.
