About this tool
No accounts, no uploads, no watermarks — just the operation you came for. Convert images between JPG, PNG, WebP and AVIF locally in your browser — no upload. 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 format conversion lose image quality?
Converting to lossless formats like PNG retains 100% of the original quality; converting to JPG, WebP, or AVIF uses high-fidelity encoding with negligible visual difference. If the input image has transparency, converting to JPG fills transparent areas with white, while PNG, WebP, and AVIF preserve transparency.
Can I process multiple files in bulk?
This page converts one image at a time; for bulk conversion use the Batch Image Processing tool (compress / resize / convert), which exports a ZIP when done.
Is the processed file still editable?
The result is a new image file in the selected format; the original is left unchanged.
