What is this image compressor for?
This online image compressor helps reduce file size for many images at once without installing software. It is useful for product photos, websites, landing pages, social media posts, ecommerce listings, email attachments, and files that need to load faster on mobile devices.
Supported compression modes
Tool Office supports multiple compression workflows: reducing image dimensions by scale, compressing toward a target KB or MB size, and smart compression for cleaner visual quality. You can export images automatically or choose JPG, WEBP, or PNG depending on your use case.
Should I use JPG, PNG, or WEBP?
WEBP is usually a strong choice for web images because it keeps good visual quality with smaller file sizes. JPG is great for photos and product images that do not require transparency. PNG is better for logos, icons, or images that need transparent backgrounds, but it is often larger.
Frequently asked questions about image compression
Which image formats does this compressor support?
The tool supports common image formats such as JPG, JPEG, PNG, WEBP, GIF, BMP, and AVIF when your browser can read them. For export, you can choose auto, JPG, WEBP, or PNG.
Will compressing images make them blurry?
Image quality depends on the compression settings you choose. For product photos, use smart compression or a moderate quality value to reduce file size while keeping the image visually clean.
Should I export as JPG, PNG, or WEBP?
JPG is suitable for photos and general product images without transparency. PNG is suitable for logos, icons, and transparent images but can be larger. WEBP is usually best for websites and landing pages because it keeps good quality with smaller file sizes.
Can I compress multiple images at once?
Yes. You can upload multiple images, choose a compression mode, and download each result or download all optimized images at once.
Are my images uploaded to a server?
No. Your images are processed directly in your browser. Tool Office does not receive, store, or upload your images during compression.
How does target file size compression work?
When you set a maximum KB or MB value, the tool tries to reduce quality and image size until the output file is close to your limit. Very large or detailed images may not always reach the exact target, but the file size can still be reduced significantly.
Does compression change image width and height?
It depends on the mode. Scale mode and smart compression with a maximum width can reduce dimensions. Quality-only compression may keep the original width and height.
When should I use this image compressor?
Use it when you need lighter images for websites, landing pages, ecommerce marketplaces, Facebook, TikTok Shop, email, chat apps, or any place where faster loading and smaller file size matter.
