How to compress images with Squoosh using your Android mobile

Access Squoosh from your Android mobile browser.
What formats and advanced options does Squoosh offer on Android?
One of the great advantages of Squoosh over other compressors is the number of modern codecs which it supports. From your mobile you can convert your images to WebP, AVIF, MozJPEG, OxiPNG, JPEG/PNG Browser, JPEG XL or QOIAmong other things, this allows you to choose the format that best balances quality, compatibility, and weight for each case.
In the right panel you will always find a section for the output formatFor web and blog projects, the most interesting ones are usually WebP (highly compatible and lightweight) and AVIF (Very high compression with great visual quality). If you need absolute compatibility with older systems, you can use JPEG o Browser JPEG.
Depending on the chosen format, Squoosh will display specific controls. The slider of Quality It typically ranges from 0 to 100 and allows you to decide how much visual information is preserved. Higher values ​​result in higher quality and larger file sizes, while lower values ​​significantly reduce file sizes but can introduce visible artifacts if compression is overdone.
Some codecs include a setting for Effort or effort level. This parameter defines how much time Squoosh spends analyzing the image to achieve the best possible compression. A high effort level takes longer to process the photo, but usually results in smaller files while maintaining good quality, which is useful if you work with slow connections or plan to optimize many images for your website.

For websites, working with widths between [insert range here] is usually sufficient. 1.000 and 1.600 pixels in main images and slightly lower values ​​in the content, which reduces the weight without being noticeable at first glance on mobile screens.
Another very interesting option is Reduce Palettewhich reduces the number of distinct colors used in the image. This is especially effective in graphic designs, icons or illustrationswhere millions of colors are often not needed. The control of Dithering It introduces a noise pattern that helps to disguise the reduction of the palette, avoiding banding or abrupt jumps in the gradients.
Squoosh also allows you to decide whether to keep the transparency channels in formats that support it, such as PNG or WebP. This is key when optimizing logos or graphics with non-rectangular backgrounds so that they continue to display correctly on colored backgrounds or images.
In the advanced settings section for each codec, you'll find more technical parameters, such as color optimization, encoding mode, and color subsampling management. If you're not experienced in image editing, you can leave these at their default values, as Squoosh's standard configuration is designed to offer good balance between quality and weight without needing to touch anything else.

Recommended settings and mistakes to avoid when using Squoosh
To get the most out of Squoosh on Android, it's advisable to have a few things reference valuesIn images for the web, a width between 1.200 and 1.600 pixels with qualities around 70% in WebP or 40-50 in AVIF usually gives very light and visually sharp results.
On social media platforms like Facebook or Instagram, working with a width of around 1.080-1.200 pixels and quality settings close to 80% helps avoid aggressive recompression from the platform itself. For YouTube thumbnails, the standard size is 1.280 × 720 pixels, where medium-to-high quality JPEGs still perform very well.
To send photos via WhatsApp without losing quality, you can prepare them in WebP or JPEG at 1.280 pixels wide and 70-85 quality, and send them as Valid identity document instead of as a normal photo, so that the app does not re-encode or re-compress them.
Among the most common mistakes are uploading giant images of 3.000 or 6.000 pixels "just in case", using such low qualities that artifacts appear in texts or borders, choosing JPEG for logos with transparency (losing the transparent background) or forgetting the sRGB color space, which is the most recommended so that the colors look correct on mobiles and on Windows.
