R8 ByteFit

Get your images under the upload limit. Choose a maximum size in KB, compress a batch, then compare the results before saving. TRY FIRST, UNLOCK ONCE Download for free and successfully process 3 of your own images on each device. Built-in samples are free. Failed attempts and cancellations before completion do not count; changing settings for the same original does not use another free image. Completed images remain exportable. A one-time App Store purchase unlocks more new images, with no subscription, automatic renewal or automatic charge when the trial ends. There is no total image limit after unlocking; each batch supports up to 100 images. Restore on Mac, iPhone and iPad with the same Apple Account. See the purchase screen for your local price. Buying and restoring require internet access. A SIZE LIMIT YOU CONTROL Supports JPG, PNG, HEIC and static WebP. Output is JPG. Choose a limit from 10 to 20,000 KB and set the longest edge. Results are marked complete only when their actual byte count fits the limit. 1 KB = 1,000 bytes. On iPhone and iPad, the longest edge defaults to 2400 pixels; choose 800, 1600, 2400 or 4000 pixels. Keep the app in the foreground while processing. Mac also offers no extra edge limit. You control whether further resizing is allowed to reach the KB limit. LOCAL PROCESSING, ORIGINALS KEPT No app account required and no image uploads to developer servers. Select images using the system photo or file picker, preview the result and save to a location you choose. Originals are kept. Output removes source EXIF, GPS and IPTC metadata, fills transparent areas with white and uses sRGB. The interface and app name follow your language preferences, with English, Simplified Chinese and Traditional Chinese available. Compression is lossy and may soften detail or reduce resolution. ByteFit does not check every requirement of the site you upload to. Animated or multi-frame images, PDF, RAW and video are not supported. Inputs are limited to 100 MB, 60 megapixels and 12,000 pixels per edge. Save temporary results promptly. Support: feedback@r8game.com
