brucet Posted August 15, 2022 Share Posted August 15, 2022 Edited a scanned image, then tried to save as .jpg, but no option to control file size. Original resolution is not good enough to justify a 1.4Mb file size. How can I control .jpg compression/file size when saving from Affinity? Photoshop [Command+S] usually pops up a window to adjust file size; [Command-Shift-S > Replace] always does. Quote Link to comment Share on other sites More sharing options...
thomaso Posted August 16, 2022 Share Posted August 16, 2022 Use Export, not Save. There you get all file types and options. Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
brucet Posted August 16, 2022 Author Share Posted August 16, 2022 Thanks. Export is clunky, but it works. There are 5 resample choices, including Lanczos separable and non-separable. Do you know what those mean and why I would want to choose any one of them? Quote Link to comment Share on other sites More sharing options...

thomaso Posted August 16, 2022 Share Posted August 16, 2022 Photoshop has resampling method options, too, but hidden in its app preferences. "Bit clunky but works" 😉 This thread contains in a few posts some comparison between bicubic and lanczos: Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
