Frequently asked questions

Will quality drop?+

JPEG and WebP are lossy. Lower quality means smaller files. Optional target size iteratively lowers quality for those formats.

Are my images private?+

Yes. Compression runs with the Canvas API in your browser only.

How do I compress a photo for email or a CMS upload limit?+

Upload the image in ToolVera’s compressor, lower quality or set a target file size, then download the result. Processing stays in your browser so originals never leave your device.

Should I use JPEG, PNG, or WebP for compression?+

JPEG or WebP work best for photos when you need smaller files. PNG suits graphics with sharp edges or transparency but often stays larger after compression.
