GIF Byte Budget: Fit an existing GIF under a byte cap, offline

GIF Byte Budget handles one small job: taking an existing animated GIF and checking whether it can fit a chosen byte cap without uploading it. Open the downloaded HTML in desktop Chrome, choose a supported GIF, enter a byte limit, and optionally allow proportional resizing down to a minimum you set. Compare the result before saving. The original is untouched. This is a limited $5 release, not a video editor or a universal GIF compressor. It can report no fit, and smaller dimensions lose detail. Input limits include 10 MB, 60 frames and the canvas/frame-pixel limits described on the product page. There is no promise of acceptance by any particular website or of best-possible compression. Created with AI assistance; bundled encoder notices are included. Gallery images show synthetic internal tests, not customer files or typical compression savings. The app is an early release and is labeled a local prototype. If you try it, useful feedback is whether you completed your own byte-cap task and where the supported-input limits prevented it.
