Best sites for JPEG compression: best online image compressors

TinyPNG

TinyPNG is a lightning-fast programme for compressing images in WebP, PNG, and JPEG formats without sacrificing quality. It “selectively decreases the number of the colours.” You can compress up to 20 photographs with a maximum file size of 5MB with the free plans.

The pro plan operates similarly and removes these restrictions for a nominal annual price. Furthermore, it is compatible with translucent graphics and animations. TinyPNG also includes an Adobe Photoshop plugin that aids in compression without requiring you to leave your favourite image editor.

Compressor

Compressor has sophisticated features as well as support for JPEG, PNG, SVG, GIF, and WEBP file formats. Lossy and lossless compression techniques are available. The former is concerned with maximum compression with no noticeable quality loss (akin to TinyPNG), whereas Lossless is concerned with maximum colour retention with little compression.

CompressNow

The Best Sites for JPEG Compression Online as of 2024

CompressNow is a free image compression programme with a 9 MB size limit that you can use on ten photographs at a time. This works with JPG, JPEG, GIF, and PNG files and allows you to choose the compression level ahead of time.

There is no paid tier or API integration. As a result, this is best suited for beginners with one-time compression tasks. Every 30 minutes, the website validates the deletion of processed photographs, which is ideal for data privacy. CompressNow’s best feature is the compression options it provides. As a result, you can experiment with different percentages and choose the best one.

Kraken

Even in its free tier, Kraken enables bulk compression, with a 1MB file limit on individual photos. Images in JPEG, PNG, GIF, Animated GIF, and SVG formats can be compressed using three modes: Lossy, Lossless, and Expert. Lossy obviously works for maximum compression, Lossless preserves quality, and Exert mode allows you to customise the compression parameters.

OptimiZilla

OptimiZilla is another freeware image compression application for beginners that allows you to optimise 20 photos at once. It supports JPEG, GIF, and PNG image formats with no size restrictions. At first glance, it appears to be quite simple. However, the real fun begins when you add the topic image(s). This function allows for bulk uploading and individual image optimisation in a slideshow-style layout, followed by bulk downloading.
