A photo from a modern smartphone can be 5-10MB — far too large for a website, email, or messaging app. Our image compressor reduces file size by 40-85% using intelligent compression algorithms that preserve visual quality while removing redundant pixel data the human eye cannot perceive.
Lossless compression reduces file size without discarding any data — the result is pixel-perfect identical to the original. It achieves modest reductions of 10-30%. Lossy compression discards image data that the eye is unlikely to notice — imperceptible detail in smooth gradients and background areas. This achieves 50-85% reductions with results that look identical to most viewers. Our compressor uses lossy compression at a quality level that provides maximum reduction while keeping images sharp.
We compress JPG, PNG, and WebP. JPG is best for photographs. PNG is better for graphics, logos, screenshots, and images with text since it supports transparency. WebP offers smaller files than both — converting to WebP for web use is worth considering if your platform supports it.
Images typically account for 50 to 70 percent of a webpage's total file size. Unoptimised images are the single most common cause of slow-loading websites. Google's Core Web Vitals include Largest Contentful Paint which measures how quickly the main image or content block loads. Compressing images before uploading them to your website can improve these scores dramatically, boosting both user experience and search engine rankings at the same time.
Image compression involves a quality versus size trade-off. At 80 to 85 percent quality, most images look indistinguishable from the original while achieving 60 to 70 percent file size reduction. Below 70 percent quality, compression artifacts become visible especially in areas with fine detail, sharp edges, and smooth gradients. For product photography where quality is paramount, use 85 percent quality. For thumbnails and background images, 70 to 75 percent provides an excellent balance between quality and speed.
From university students working on assignments to HR professionals processing documents, from small business owners managing invoices to software developers working with data formats, Quickly.fit tools are used daily by people across every profession and every industry. The common thread is the need for reliable, fast, professional results without the cost and complexity of dedicated desktop software subscriptions that are not justified for occasional or moderate use.
Quickly.fit is actively maintained and regularly updated to ensure compatibility with the latest file formats, browser standards, and security requirements. When browsers update their capabilities, our tools are updated to take advantage of improvements. When new file format versions become common, our converters are updated to handle them. User feedback directly shapes what gets improved next. This ongoing investment in quality is what separates a genuinely useful tool from one that works when first built but gradually becomes unreliable as the web evolves around it.
