About Image Compression

Image compression shrinks file size by removing data your eyes are unlikely to notice. There are two approaches. Lossy compression (used by JPEG and WebP) discards fine colour detail and high-frequency texture, which can cut file size by 60-90 % with little visible change. Lossless compression (used by PNG and lossless WebP) rearranges pixel data more efficiently without discarding anything, typically saving 10-30 %.

O tamanho correto do alvo depende de onde a imagem será usada. As fotos de passaporte e identidade para portais governamentais geralmente precisam ter menos de 50 KB. As imagens principais do site têm melhor desempenho entre 80 e 150 KB para carregamento rápido sem desfoque visível. As fotos de produtos de comércio eletrônico geralmente têm entre 100 e 200 KB para equilibrar detalhes e velocidade da página. As plataformas de mídia social recompactam os uploads automaticamente, portanto, começar com um arquivo limpo de 200 a 500 KB oferece o melhor resultado.

If you already know the exact format you need, jump to a dedicated tool: compress JPEG, compress PNG, compress WebP, ou compress HEIC. If you are comparing options or need a general-purpose compressor, start here.

How to Compress Images Online

Three simple steps to reduce image file size — no software, no sign-up required.

Upload Your Images

Upload up to 50 images simultaneously for batch compression. Supports JPG, PNG, WebP, BMP, TIFF, GIF, HEIC, and SVG.

Choose a Target Size

Pick a target file size — 50 KB, 100 KB, 200 KB, 500 KB, or 1 MB. Our engine adjusts quality automatically to hit the target while keeping the image sharp.

Download Compressed Images

Download files individually or as a single ZIP. Processing takes 2-5 seconds per image. Files auto-delete after 2 hours for privacy.

Why Choose Our Image Compressor

Universal Format Support

Compress any image format with specialised algorithms — JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF, GIF, SVG, and more.

Segmentação por tamanho preciso

Need exactly 50 KB for a form upload? Our engine iterates through quality levels to find the setting that hits your target. For JPEG it adjusts quantisation; for PNG it uses palette reduction.

Processamento em lote

Comprima até 50 imagens de uma vez com um único tamanho de destino ou personalize cada uma individualmente e baixe tudo como um ZIP.

Fast Server-Side Processing

Compression runs on our servers in 2-5 seconds per image — no browser slowdown, no plugins, and works on all devices including phones and tablets.

Privado e Temporário

Uploads travel over 256-bit SSL encryption. We store nothing permanently — all files are automatically deleted within 2 hours of processing.

Improve Core Web Vitals

Lighter images mean faster Largest Contentful Paint (LCP) scores. Reducing page weight by 60-70 % can move your site from "Needs Improvement" to "Good" in Google PageSpeed.

Image Compressor FAQ

Quick answers about target file sizes, expected quality, privacy, and the best ways to reduce image file size.

How do I compress a file for free with the Image Compressor?

Pick the format and target size you need, upload your file, and click Compress. The result downloads in seconds — free, with no watermark and no account required.

How small can I make my file?

You can target sizes from 50KB up to 2MB. The Image Compressor keeps quality as high as possible while hitting the size you choose, so the file still looks good and fits the limit you need to meet.

Will compressing reduce quality?

A smaller file always involves some trade-off, but the Image Compressor optimises for perceptual quality — images stay sharp at normal viewing size and document text stays crisp. Smaller reductions are effectively invisible.

What file formats does the Image Compressor support?

The Image Compressor handles JPG, PNG, PDF, WebP, and HEIC files. Each format has its own dedicated compression tool with format-specific optimizations — JPG uses DCT quality adjustment, PNG uses palette quantization, and PDF targets embedded images while keeping text sharp.

Are my files kept private during compression?

Yes. Uploads use an encrypted HTTPS connection, compression runs on an isolated worker, and both your original and the compressed file are deleted automatically within a short window — nothing is stored, shared, or used for training.
