What Is an Image Compressor?
An image compressor reduces the file size of photos and graphics without noticeably affecting visual quality. Smaller images load faster on websites, save storage space on your devices, and help you meet email attachment limits. Tooliva's online image compressor uses advanced compression algorithms to shrink JPEG, PNG, and WebP files right in your browser, so you get smaller files in seconds without installing any software or creating an account.
Why Compress Images Online with Tooliva?
Page speed is a Google ranking factor, and oversized images are the number-one cause of slow websites. Tooliva's free image compressor lets you optimize photos for the web in two clicks. There are no watermarks, no sign-up walls, and no file-size caps. Because compression happens entirely in your browser, your original files are never uploaded to a server, keeping your photos private and secure.

Frequently Asked Questions
Q: Will compression make my image look worse?
At moderate quality settings the difference is invisible to the human eye. You can adjust the compression level and preview the result before downloading, so you stay in full control of the quality-versus-size trade-off.
Q: What is the maximum file size I can compress?
Tooliva handles files well beyond typical web and photography needs. If your browser can load it, the compressor can process it. There is no hard server-side cap because everything runs locally in your browser.
Q: Is my image uploaded anywhere?
No. All compression uses the Canvas API inside your browser. Your files are never sent to a remote server, so your photos remain completely private.
Q: Can I compress PNG files with transparency?
Yes. The compressor preserves the alpha channel in PNG files, so transparent backgrounds remain intact after compression.
