Supports PNG, JPEG, WebP, AVIF, GIF, BMP, HEIC/HEIF — pick several at once

This is a free online image compressor that shrinks JPG, PNG, WebP and other images right in your browser, reducing file size with almost no visible loss in clarity. It offers three ways to compress: by quality, to a target size (such as 100KB or 200KB), or by capping the longest edge. Beyond keeping the original format you can also convert to WebP or AVIF for even smaller files. Compress dozens of images at once and see a live before/after comparison with total savings. Everything happens locally — your images are never uploaded to any server, so it's fast and private. It also strips the original metadata, with no watermark and no limits.

How to compress images

  1. 1

    Add images

    Drag your images into the upload area or click to choose. Add several at once — PNG, JPEG, WebP, AVIF, GIF, BMP and HEIC/HEIF are all supported.

  2. 2

    Pick a compression mode

    Choose to compress by quality, by target size (KB), or by longest edge, and decide whether to keep the original format or convert to WebP / AVIF for smaller files.

  3. 3

    Compress and download

    Click “Compress” to encode locally in your browser. Review the before/after sizes and savings, then download each image or grab them all as a ZIP — nothing is uploaded.

Highlights

Compress to a target size

Enter a target KB and the tool binary-searches quality and resolution to shrink images to within 100KB, 200KB and similar limits — perfect for upload size caps.

Three compression modes

By quality, by target size, or by longest edge — whether you want to preserve clarity, lock the file size, or reduce dimensions, there's a mode for your case.

Convert to WebP / AVIF

Beyond keeping the original format, convert to WebP or AVIF: at equal quality the file is usually 30–50% smaller, slimming images further for the web and storage.

Batch compression

Drop in dozens of images at once, compress them all with the same settings, then download everything as a single ZIP — no more one-by-one work.

Before/after · total savings

Every image shows original → new size with a reduction percentage, and the top summarizes the total savings across all images, so the effect is obvious at a glance.

Local · strips metadata

Everything runs in your browser with no upload, and re-encoding strips EXIF and other metadata — protecting your privacy while shrinking the file even more.

Common uses

Meet upload size limits

Shrink photos under 100KB or 200KB to easily pass hard size requirements on forms, visa applications, exam registrations and e-commerce dashboards.

Lighten sites and emails

Compress and convert to WebP / AVIF to cut page image weight, speeding up loads, saving bandwidth and improving SEO and Core Web Vitals.

Shrink large phone photos

Phone photos are often several MB — cap the longest edge at 1920px and compress to share, upload or archive without filling up your storage.

Slim down a whole album

Compress an entire batch of images at once, download them packaged as a ZIP, and quickly free up space or upload to cloud drives and social platforms.

FAQ

Are my images uploaded to a server?

No. All compression happens locally in your browser — images are never uploaded to any server and don't pass through any backend. Even offline, already-loaded images keep working, so your privacy is fully protected.

Can I compress an image to a specific size, like 100KB or 200KB?

Yes. Switch to “By target size”, enter the KB you want, and the tool automatically binary-searches quality and, when needed, lowers resolution to fit within that size. Note that only lossy formats like JPG / WebP / AVIF can hit an exact target — lossless formats such as PNG can only approach it by shrinking dimensions.

Will compression hurt image quality?

When compressing by quality you can freely adjust the quality value — higher means closer to the original. Around 80% usually strikes an excellent balance between size and clarity, with differences barely visible to the eye. Lower it for a smaller file; the tool shows before/after sizes live so you can weigh the trade-off.

Which image formats are supported?

Input supports PNG, JPEG, WebP, AVIF, GIF, BMP and Apple's HEIC/HEIF; output can keep the original format or convert to WebP or AVIF for smaller files. Common tasks like compress PNG, compress JPG and compress WebP all work in one click.

Can I compress multiple images at once?

Yes. Batch is supported: drop in or select several images, compress them with the same settings, then download each one or click “Download ZIP” to grab them all at once.

My PNG barely got smaller — what should I do?

PNG is lossless, so the quality setting has no effect and it often won't shrink. Pick WebP or AVIF under “Output format” instead — they compress photos and complex images far better than PNG, usually cutting the size significantly while staying sharp.

Does compression add a watermark or keep private info?

No watermark is added. On the contrary, re-encoding strips the original EXIF and other metadata (such as camera model and GPS location), which both reduces the file size further and helps prevent privacy leaks.
