How do I compress a file to an exact target file size?
Wexporting's Target Size Mode exports an image, video, or animated loop to an exact size limit — for example exactly 1 MB to fit an upload cap — without manual trial and error.
How does Target Size Mode work?
In Wexporting you choose Target Size Mode and enter the size you need, such as 1 MB. Wexporting then adjusts quality automatically to land at or under that size, processing the file locally on your PC so it never leaves your device.
Can I export several target sizes at once?
Yes. Wexporting can target multiple sizes in a single pass — for example 1 MB, 2 MB, and 3 MB simultaneously — and you can combine this with batch processing to do it across many files at once.
Which file types support a target size?
Target Size Mode works across Wexporting's supported formats — images (AVIF, WebP, PNG, JPG), video (MP4), and animated loops (GIF, WebM). See the full format reference.
