Image Compressor & Format Converter
Compress and convert JPEG/PNG/WebP images to shrink file size.
How it works
Drag in one or more images and re-encode them as compressed JPEG, PNG, or WebP, with an adjustable quality slider for lossy formats. Each image shows its original size, output size, and percentage saved before you download it.
- Drag and drop image files onto the drop zone, or click to select files (multiple at once supported).
- Choose an output format — WebP typically gives the smallest files for photos.
- Adjust the quality slider for JPEG/WebP to balance size against visual fidelity.
- Download each compressed image individually once you're happy with the result.
Common use cases
- Shrinking photos before uploading them to a website to improve page load speed.
- Converting PNG screenshots to WebP or JPEG to reduce file size for email or chat attachments.
- Batch-compressing a set of product images before adding them to a CMS.
- Testing how a quality setting affects file size before automating the same conversion in a build pipeline.
FAQ
- Which format should I pick?
- WebP generally gives the best compression for photos with wide browser support today. Use PNG when you need transparency or lossless quality, and JPEG for maximum compatibility with older tools.
- Why doesn't the quality slider appear for PNG?
- PNG is a lossless format, so there's no quality trade-off to adjust — recompression only removes redundant metadata and optimizes encoding.
- Is there a file size or count limit?
- You can process multiple images at once; very large images may take a moment longer to process.
