Image compressor and format converter
Resize, compress and convert JPEG, PNG or WebP locally. Your image never leaves this browser.
JPEG, PNG or WebP only. Maximum 10 MB, 24 megapixels and 8,192 pixels per side.
Private preview
Choose an image to preview and process it locally.
Local compression and conversion
The browser decodes the image, draws it to a size-limited canvas and encodes a new JPEG, PNG or WebP file.
Deliberate safety limits
Large decoded images can exhaust memory even when the file is small. Limits reduce freezes; metadata and animation are not preserved.
No image upload
Source, preview and output stay in this browser and are not sent, stored, added to the URL or shared with analytics. The work area contains no advertising.
Frequently asked questions
Does this tool send my input to a server?
No. The tool runs in this browser after you choose to use it. Your pasted content or generated result is not added to URLs, storage, analytics or server requests.
Does a clean result guarantee that an email or account is safe?
No. These tools explain technical clues and reduce routine risk, but they cannot replace your judgment, malware protection, account security controls or advice from a qualified security professional.
