Why local image compression, specifically
Most image compressors run in the cloud: you upload a file, a server processes it, and you download the result. That round trip means bandwidth, wait time, file size limits tied to server policy, and — for anything confidential — a third party briefly holding your data.
A local compressor removes all of that. Your own CPU does the work, so there's no upload, no cap on file size or batch count, and no connection required at all. This page exists to point you toward the exact scenario you're dealing with — a format question, a framework-specific workflow, or a direct comparison against a tool you use today.

Frequently asked questions
What is the best image compressor?
The best choice depends on your workflow. For a native, private, no-upload compressor covering PNG, JPEG, WebP, AVIF, and GIF on Mac and Windows, TinyPixels covers the general case. For a specific need — a particular framework, platform, or format conversion — the dedicated pages linked on this page go deeper into that exact scenario.
Do I need a different tool for every image format?
No. A single well-built compressor can handle PNG, JPEG, WebP, AVIF, and GIF with format-appropriate settings for each — lossless or lossy PNG, mozjpeg-based JPEG, and modern format conversion, all in one app rather than juggling separate single-format tools.
Should I compress images locally or use a cloud tool?
Local compression avoids uploading files to a third party, has no file size or batch caps, and works without an internet connection. Cloud tools can be convenient for a single one-off image, but for regular use, confidential content, or any real volume, local compression is generally the better default.
What image format should I use for my website in 2026?
WebP is the safe, near-universally supported default for most sites. AVIF produces smaller files still and is worth using as a primary format with a WebP fallback if your audience skews toward modern browsers. PNG remains the right choice for source and master files you plan to edit further.
