Why Compress Images Online?
Large image files can slow down websites, take extra storage, and fail to upload as email or social attachments. Compressing an image reduces file size so it is easier to share and store. How much the file shrinks, and how it looks afterward, depends on the original image and the quality settings you choose.
This compressor runs in your web browser. Images are not uploaded to a remote server for processing.
Key Features & Benefits
Built for browser-based compression, format choice, and simple quality controls:
Browser-Based Processing
Compression runs locally in your browser using the Canvas API. Files are not sent to a server for processing.
Multi-Format Support
Upload JPG, JPEG, PNG, WebP, or GIF. Output formats are JPEG, PNG, and WebP. Animated GIFs are flattened to a still image (typically the first frame).
Quality Presets and Resize
Use High, Very High, or Maximum presets, or set JPEG/WebP quality yourself. You can also cap width or height. JPEG and WebP are lossy. PNG-to-PNG can sometimes increase file size.
Free, No Registration
Compress one image at a time for free, with no account and no watermarks. Maximum file size is 20MB.
Frequently Asked Questions (FAQ)
Will image compression reduce the visual quality of my photos?
It can. JPEG and WebP use lossy quality settings (presets default to Very High, about 80%). Lower quality makes a smaller file. Results vary by image, and an 80% size reduction is not guaranteed. PNG-to-PNG may not get smaller.
Is it safe to compress private or sensitive images here?
Yes. Compression runs in your browser. Images are not uploaded to or stored on a processing server.
Which image file formats are supported for compression?
You can upload JPG, JPEG, PNG, WebP, and GIF. The compressed file is saved as JPEG, PNG, or WebP โ not GIF.
