How to compress an image
Nenhuma conta ou upload é necessário. Pick files, choose a quality level, and download the optimized copies.
- 01
Select images
Drop one or more JPG, PNG, WebP, AVIF, GIF, BMP, ICO, or TIFF files, or paste an image directly.
- 02
Set quality and format
Use the quality slider to balance detail and file size. Keep the original format or export to JPEG, WebP, AVIF, or PNG.
- 03
Compare and download
Review the size difference, compare the visual result, then download one file or a ZIP of the batch.
Common image compression scenarios
A smaller image is easier to email, faster to load, and more practical to store. Here are a few useful starting points.
Email attachments
Compress large camera photos before sending them so the message stays within attachment limits and downloads faster.
Web pages and blogs
Use WebP or AVIF for modern websites to reduce page weight while keeping product photos and hero images sharp.
Social media uploads
Create lighter copies for posts, profiles, and thumbnails without changing the original files in your library.
Product catalogs
Batch-compress product images to speed up storefront pages and make asset handoffs easier for your team.
Private by design
Images are decoded and encoded locally no seu navegador with Web Workers and WASM codecs. They are not sent to a server, and the page does not need an account to process them. Baixared output remains under your control.
FAQ
Compressor de imagens FAQ
Are my images uploaded?
No. Processing happens no seu navegador, so the image bytes stay no seu dispositivo during compression.
What quality should I use?
75% is a useful starting point for photos. Increase it when fine detail matters, or lower it when the smallest file is the priority.
Which format makes the smallest file?
WebP and AVIF are often smaller than JPEG at similar visual quality. JPEG is still the safest compatibility choice, while PNG is best when transparency or lossless edges matter.
Can PNG images be compressed?
Yes. PNG output can reduce the color palette for arquivo menors. For photographic PNGs, converting to WebP or JPEG usually saves more space.
Does it work on phones?
Yes, as long as the mobile browser supports the selected image format. For large batches, a desktop has more memory and CPU headroom.
How many files can I process?
You can add multiple images in one batch. Each input is limited to the size shown in the uploader; available device memory can affect very large batches.
