How to Use This Tool
Upload Your Images
Click the upload area, drag and drop files, or paste from clipboard (Ctrl+V). Supports JPEG, PNG, WebP, GIF, TIFF, BMP, AVIF, and SVG up to 25 MB per file, 100 MB total, and up to 10 files.
Compress
Click Compress or Compress All. Each image is optimized automatically for its format. A spinner shows progress on each thumbnail.
Review Results
Each thumbnail displays the original and compressed size along with the percentage saved. If compression would increase the file size, the original is kept.
Download
Download a single compressed image directly, or download all as a ZIP archive. Files are saved with a -compressed suffix.
Frequently Asked Questions
Does compression reduce image quality?
▼
Yes, but imperceptibly at the levels this tool uses. The compressor automatically finds the optimal balance between file size and visual quality. For JPEG and WebP, it uses advanced encoders that discard only imperceptible details. For PNG, it reduces the color palette intelligently. The result looks virtually identical to the original.
Is my image uploaded to a server?
▼
No. This tool runs 100% in your browser. Your images never leave your device. All compression happens locally using advanced compression techniques. No data is transmitted, no cookies are used, and no third-party services have access to your files.
What is the maximum file size?
▼
Each file can be up to 25 MB, with a total limit of 100 MB across all uploaded files. You can upload up to 10 images at once.
Why did my file size not change?
▼
If the compressor determines that compression would produce a larger file than the original, it automatically keeps the original. This happens with images that are already well-optimized or very small. The thumbnail will show 0% change in this case.
Which format gets the best compression?
▼
JPEG photographs typically see the largest savings (60-85% smaller) because the JPEG encoder is highly optimized for photographic content. PNG graphics with many colors also compress well. WebP images are already well-compressed, so savings may be smaller.
Can I compress images without losing quality?
▼
PNG compression tests both lossless and lossy strategies (palette quantization to 64, 128, or 256 colors) and picks the smallest result. The lossy PNG output is visually near-identical to the original. For JPEG and WebP, compression is lossy but tuned to be visually imperceptible.
Does this tool strip EXIF data?
▼
Yes. The compression process re-encodes the image, which removes EXIF metadata (camera settings, GPS, date). If you need to preserve metadata, back it up before compressing.
Can I compress GIF, TIFF, or BMP images?
▼
Yes. GIF, TIFF, BMP, AVIF, and SVG images are accepted as input. They are converted to JPEG during compression since JPEG provides the best compression for these formats.
Will my images be saved if I close the browser?
▼
Yes. Your uploaded images and compression results are automatically saved in your browser's IndexedDB storage. When you return to this page, everything is restored exactly as you left it. Click Clear All to remove all stored data.
How does batch compression work?
▼
Upload up to 10 images at once via drag & drop, file picker, or clipboard paste. Click Compress All to process every image sequentially. Each thumbnail shows its own progress spinner and result. Download all compressed images as a single ZIP archive.
What Is Image Compressor?
Image Compressor is a free browser-based tool that shrinks your image file sizes while keeping them looking great. It supports JPEG, PNG, WebP, GIF, TIFF, BMP, AVIF, and SVG formats and automatically finds the best compression settings for each image — so you get the smallest file size without visible quality loss.
Everything runs 100% in your browser. Your images are never uploaded to any server. You can compress multiple files at once, compare original and compressed sizes, and download results individually or as a ZIP archive.
Features Explained
JPEG Compression
▼
JPEG photos are compressed with an advanced encoder that produces significantly smaller files than standard tools — typically 60-85% smaller while keeping the image visually identical.
PNG Compression
▼
PNG files are optimized by intelligently reducing the color palette. Multiple quality levels are tested automatically and the smallest result is picked for you.
WebP Compression
▼
WebP images are tested at 10 different quality levels. For smaller images, all levels are tested in parallel for speed. For large images (over 4 megapixels), levels are tested sequentially to prevent memory issues. The tool picks the smallest result automatically.
Batch Processing
▼
Upload and compress multiple images at once. Each file is processed with its own progress indicator, so you can track the status of every image.
Smart Size Check
▼
If compression would produce a file larger than the original, the tool automatically keeps the original. You never end up with a bigger file than you started with.
ZIP Download
▼
When compressing multiple images, download all results as a single ZIP archive. Each file inside is named with a -compressed suffix for easy identification.
Clipboard Paste
▼
Press Ctrl+V to paste an image directly from your clipboard. Great for compressing screenshots without saving them as files first.
EXIF Metadata Stripping
▼
Compressed images automatically have EXIF metadata (camera settings, GPS coordinates, date, orientation) removed during re-encoding. This protects your privacy when sharing images online.
Auto-Save Progress
▼
Your uploaded images and compression results are saved automatically in your browser's IndexedDB. Refreshing the page restores everything so you don't lose your work. Click Clear All to remove stored data.

Tips for Compressing Images
Choose the right format
Use JPEG for photographs with many colors. Use PNG for graphics, logos, or images with transparency. Use WebP for the best balance of quality and size on modern browsers.
Resize before compressing
If your image is 4000px wide but will display at 800px, resize it first using our Image Resizer tool. Compression works on the pixels you have — fewer pixels means a much smaller file.
Compress before uploading to your site
Most CMS platforms serve images as-is. Compressing before upload ensures every visitor gets the optimized version without relying on server-side processing.
Check the percentage saved
Each thumbnail shows the compression ratio. If a file only saves 1-2%, it was likely already optimized. Focus effort on files with the largest savings.
Use batch mode for bulk work
Upload up to 10 images at once (25 MB each, 100 MB total) and compress them in a single pass. Download the ZIP to get every file in one click.
Original is kept when compression doesn't help
The tool automatically keeps the original file if compression produces a larger result. You never need to worry about accidentally increasing file size.
Paste screenshots directly
Press Ctrl+V to paste an image from your clipboard. Great for quickly compressing screenshots without saving them as files first.
JPEG photos see the biggest savings
JPEG photographs typically compress 60-85% smaller because the JPEG encoder is highly optimized for photographic content. PNG and WebP savings are smaller but still significant.
EXIF metadata is automatically stripped
Compressed images have EXIF data (camera info, GPS coordinates, date) removed during re-encoding. This protects your privacy when sharing images online.
Your work persists automatically
Your uploaded images and compression results are saved to IndexedDB with a 500ms debounce. Refresh the page and everything is restored. Click Clear All to start fresh.
