- Target size is best-effort, so always check the final file size and visual quality.
Frequently asked questions
Will the result be exactly 500KB?
Not always. Pixora uses a best-effort target because image content and browser encoding affect the final file size.
Can I compress multiple images to 500KB?
Yes. Upload multiple images and the same target-size settings are applied to the batch.
Does Pixora upload my images?
Core image processing happens in your browser and does not require sending the image data to a Pixora processing server.
