Why Optimize Your Images?

Compressing images before you publish them is the fastest way to speed up your website, app, or store listing.

Private & Secure

Your photos never leave your device. All compression runs locally in your browser — no uploads, no server storage, no analytics on your files.

WebAssembly Speed

Near-native compression powered by WebAssembly. Typically 3-5x faster than pure JavaScript tools.

Batch & ZIP Export

Drop a whole folder of images, review savings per file, then download everything as a single ZIP.

Smart Format Conversion

Convert PNG, JPG, and WebP in one click with a live preview so you can verify quality before downloading.

Visually Lossless

Default settings keep files looking identical while cutting size by 60-80%. Dial quality up or down for retina or thumbnails.

No Sign-up, No Watermark

No account, no trial, no usage limits, no watermark. Use it as often as you need, on as many images as you want.

Perfect for

Common ways teams and creators use our image compressor.

Product photos

Shrink ecommerce galleries so pages load faster without losing detail.

App screenshots

Prepare App Store and Play Store screenshots that meet size limits.

Blog images

Compress hero images and thumbnails for better Core Web Vitals.

Design assets

Optimize mockups, icons, and social graphics before handoff.

Batch process entire folders

Drag a folder of 30+ images onto the compressor. The tool queues every file and processes them in parallel, showing the original size, new size, and savings for each one. When you are done, download everything as a single ZIP archive with original filenames preserved.

Compare before & after

Click any thumbnail to open a full-resolution preview and compare the compressed image against the original. This makes it easy to spot any visible quality loss before you download, so you can dial the quality slider up or down for each use case.

Before and after image quality comparison

Convert formats in one click

Switch between PNG, JPG, and WebP without leaving the tool. A live preview lets you see the impact of each format instantly, and the size comparison tells you exactly how much you will save before you commit.

Which Format Should I Choose?

Picking the right format for each image is the easiest way to shrink file size without losing quality.

JPG — Best for Photos

Ideal for photographs and complex gradients. Small files, rich colors, but no transparency.

PNG — Best for Graphics

Perfect for logos, icons, screenshots, and any image that needs sharp edges or transparency.

WebP — Best for the Web

Modern format supported by all major browsers. Typically 25-35% smaller than JPG or PNG with transparency support.

AVIF — Smallest Possible

Next-gen format with the best compression. Use when file size matters most and browser support is acceptable.

GIF — Short Animations

Limited to 256 colors. Fine for tiny loops, but WebP or MP4 usually gives better quality at a fraction of the size.

SVG — Vector Graphics

Best for logos and icons. Scales infinitely without quality loss and stays tiny at any resolution.

Frequently asked questions

Quick answers to common questions about image compression.

General

Will my image look blurry after compression?

Not with the default settings. PNG quantization is designed to be visually lossless, and JPG/WebP quality above 75-85% typically produces a sharp image with minimal visible artifacts.

Are my files uploaded to your server?

No. Compression happens entirely in your browser using JavaScript and WebAssembly. Your images never leave your device.

Is there a file size limit or batch limit?

There is no server-imposed limit. The practical limit is your device's memory. Most modern laptops handle 30-50 images of 5-10 MB each comfortably.

Formats

What is the difference between PNG, JPG, and WebP?

PNG is lossless and supports transparency, best for graphics. JPG is lossy and best for photos. WebP supports both modes and is typically 25-35% smaller.

Can I convert between formats?

Yes. After loading an image, choose the output format. Converting PNG to WebP often saves 30-50% with no visible quality loss.

What is the best quality setting for web images?

For JPG and WebP, 75-85 is the sweet spot. For PNG, 128-256 colors is enough for most graphics.

Privacy & Usage

Will compression remove EXIF metadata from my photos?

By default essential EXIF data is preserved. You can optionally strip all metadata in the advanced settings for a smaller file and extra privacy.

Can I use this tool for commercial projects?

Yes. The tool is free for personal and commercial use with no watermarks, attribution, or usage limits. You retain full ownership of your images.

How is this different from TinyPNG, Squoosh, or ImageOptim?

TinyPNG uploads files to a server. Squoosh is local but single-image. ImageOptim is Mac-only. Our tool combines local privacy with batch workflow and format conversion in one interface.
