Is it possible to reduce the file size for a PNG file without actually resizing the image and not reducing the quality significantly ? about retinal HOT 3 CLOSED

Hi @mandeepm91 — Hm.. Sharp does have some parameters for controlling the quality of the output image, and also by default omits metadata (e.g. EXIF data) when writing a new image file, but I'm not sure this would cover what you're looking for.

However, incorporating such a feature into this project makes a lot of sense. Perhaps enabling the use of a tool like imagemin would be useful?

Hi @adieuadieu,
For now we switched to JPEGs because that solved our purpose but I think adding this feature might be useful. I can try implementing this in a few days using imagemin. Let me know if I can proceed.

@mandeepm91 Yes I'd welcome a PR. I haven't thought too much about how it would be best to implement the imagemin support. Perhaps extending the "outputs" support currently used for calling Sharp functions, but add a special-case "imagemin" item which must come after all other output instructions.

Would be ideal if imagemin supported accepting a buffer. I haven't looked into this.
