Hit exact file-size targets — 20KB to 2MB — or compress in bulk with a quality slider. Every tool below runs locally in your browser — batch, free, no signup, no watermarks.
Image compression is a contract negotiation with whoever receives your files — and this category gives you the leverage. The Image Compressor handles general bulk work with a live quality slider, while the dedicated target tools guarantee exact ceilings: Compress Image to 100KB, Compress Image to 50KB and Compress Image to 20KB are the sizes government forms, visa portals and email systems actually demand. Each one binary-searches quality per file, so every output is the best-looking image that fits the limit.
Compression works best as the final step of a pipeline: crop and resize first so you only encode pixels you keep, convert to WebP first when the destination accepts it for a free 25–35% saving, and compress last. When the job is done, the EXIF & DPI tools can verify what metadata survived — useful for print submissions that check DPI alongside file size. Everything on this page and every destination runs locally in your browser.
