About this tool
Everything here happens in your browser, so the file you load is the only copy that exists. Compress JPG, PNG and WebP images with adjustable quality or a target file size, and export AVIF locally in your browser. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Output covers JPG, JPEG, PNG, WEBP and more; it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded.
What formats are supported?
Supports JPG / JPEG / PNG / WEBP / AVIF and more, selectable on the page.
Will it lose image quality?
Supports both quality slider (5–95) and target file size (KB) modes. The side-by-side preview calculates real-time size reduction, savings percentage, and PSNR quality metrics to help you balance clarity and file size.
Can I process multiple files in bulk?
This page compresses one image at a time; for bulk compression use the Batch Image Processing tool, which handles multiple images at once and exports a ZIP.
Is the processed file still editable?
The result is a new compressed image file; the original is left unchanged.
