Client-side image compression with Supabase Storage
After researching a couple of different options, what I landed on was a package called compressorjs written by Chen Fengyuan. This library performs compression and resizing of images in the browser. I was a bit skeptical at first, but it's a cool project and has good browser support. How Compressorjs works is that it uses the HTML5 canvas element to read the original image data and perform lossy transformations to compress and resize the image. There's a whole bunch of transformation options. For my project, what I have found is simply changing the maximum width of the image to 600px and slightly reducing the quality has greatly reduced the file sizes.

How to compress images on client-side
I will use compressorjs, a tiny librarie (3.8 kB minzipped). Compressor.js uses the Browser's native HTMLCanvasElement.toBlob() API to do the compression work, which means it is lossy compression.

Made a Web App to reduce Image Size by up to 90%, No file Size Limit & Works Offline | compressimage.io
You don't actually need any web services. Just import the compressorjs library and the UPNG.js library on client side(frontend) and then before uploading the data to server compress the image. These libraries were actually written for frontend compression by their respective owners. https://github.com/photopea/UPNG.js (25kb) https://github.com/fengyuanchen/compressorjs (8kb)
