How It Works

How to Compress an Image in 3 Steps

No account, no upload queue, no waiting on a server. This image compressor does all the work on your device.

Add Your Images

Drag and drop files, paste from the clipboard with Ctrl / Cmd + V, or browse your device. Add as many images as you like.

Pick Quality or a Target Size

Drag the quality slider for the best balance, or type a target size in KB. Every image re-compresses as you adjust.

Download

Save images one by one, or grab the whole batch in a single ZIP archive.

Features

An Image Compressor With No Limits

Most online compressors cap your files — 10 MB here, 20 images there, and a sign-up prompt for more. This image compressor has no quotas: your device is the only limit.

100% Private

Compress images without uploading them — everything runs in your browser through the Canvas API. Once the page loads, it even works offline. Every re-encode strips EXIF metadata.

Compress to an Exact KB

Type a target — 100KB is a common one — and target-size mode hunts for the highest quality that stays under it. If quality alone can't get there, it scales the image down a notch at a time. Built for forms with hard upload caps.

Unlimited Batch, One ZIP

Drop in ten images or five hundred. There's no count limit and no per-file size quota — a batch photo compressor that never asks you to sign up for more.

Quality You Control

The quality slider re-encodes live, so you see the savings before you download. If compressing a file wouldn't actually shrink it, the tool keeps your original.

No Upload, No Waiting

Your files never leave the device, so this image compressor starts the moment you drop them in. All the work happens on your own hardware — there's no upload queue to sit in.

Free Forever

No watermarks, no sign-up, no premium tier. Batch, ZIP, target size — every feature is free, because the work happens on your machine, not ours.

Why It Matters

Why Use an Image Compressor?

Images are the heaviest part of most web pages. The Web Almanac measured a median 1,026 KB of images per desktop page — the largest contributor to page weight of any resource type . Reducing image file size cuts that number at the source.

Google's Core Web Vitals set the bar at an LCP of 2.5 seconds or less — the time until the largest image or text block renders. Compressing images, or switching them to a leaner format, cuts that load directly. An image compressor with a quality slider puts that size-versus-fidelity decision in your hands.

Before and after — the same photo compressed in the browser: smaller file, same picture.

Formats

Compress JPEG, PNG, WebP and AVIF

Output format is up to you. Auto matches whatever you put in, or pick JPG, WebP or PNG and the image compressor converts as it compresses. Browsers that can't encode WebP fall back to JPG automatically.

JPG

JPEG

The world's default photo format. JPEG is built for lossy compression of still images, which is why cameras, phones and email clients all speak it. For everyday photos, JPEG output at a medium-high quality setting is the dependable choice.

PNG

Lossless, with full transparency support. Choose PNG when every pixel has to survive — screenshots, logos, UI graphics.

WEBP

WebP

Google's format for the modern web. WebP typically runs about 30% smaller than comparable JPEGs , and it keeps transparency too. For images on a website, it's the practical default.

AVIF

Newest format, smallest files. Lossy AVIF images are around 50% smaller than JPEG . This tool reads AVIF input and converts it to WebP or JPG.

FAQ

Image Compressor FAQ

Quick answers about privacy, quality, formats and limits.

What is an image compressor?

An image compressor is a type of image optimizer — it re-encodes pictures so they take up less space and load faster. This one runs locally in your browser, so your files are never uploaded.

Will compressing an image reduce its quality?

That's the trade-off the quality slider puts in your hands — the savings update live as you drag. Most photos land between quality 75 and 85 — drag the slider and judge on the live preview before you download. If a re-encode wouldn't actually make a file smaller, the tool keeps your original.

Can I compress an image to an exact size, like 100KB?

Yes. Type a goal like 100KB. The image compressor keeps lowering quality until the file fits under it. If quality isn't enough, it scales the image down a step at a time. It's built for uploads with hard size caps.

Are my images uploaded to a server?

No. Compression runs on your device through the browser's Canvas API — zero uploads, zero storage. You can go offline after the page loads and keep compressing.

Is there a maximum file size I can compress?

There's no server-side quota — this image compressor never talks to a server. The practical ceiling is your device's memory.

Can I compress multiple images at once?

Yes — batch compression has no file-count limit. Download results one by one, or pack the whole batch into a single ZIP archive. Nothing sits in a server queue in between.

Which formats does the image compressor support?

Input: JPG, PNG, WebP, AVIF and BMP. Output: Auto (matches the input), JPG, WebP or PNG — on Safari, WebP output falls back to JPG. SVG, HEIC and animated GIFs aren't supported.

Does it work offline?

Yes — it works in any modern browser, on desktop and mobile, with nothing to install. Once the page has loaded, every step runs locally with no network requests. Turn off Wi-Fi and the compressor keeps working.

Which output format should I choose?

Auto matches whatever you put in — to compress JPG or PNG in place, stay on Auto. For web use, WebP output gives you smaller files than JPEG at similar quality. Pick PNG for lossless output or transparency.

How do I meet government-form or email size caps?

Use target-size mode and type the cap — 100KB and 20KB come up often. The image compressor holds quality as high as it can under the limit, and every result ships without EXIF metadata.
