Compress Image

To compress image files, add them to the box above, keep the Recommended level and press the red button. In a few seconds every picture is smaller, usually by half or more, and a before and after slider lets you check that nothing visible has changed. Then download one file, or all of them together as a ZIP.

This image compressor works inside your browser, so your pictures are not uploaded anywhere. It handles JPG, PNG, WebP, iPhone HEIC, AVIF, GIF and BMP files, keeps transparency, removes hidden camera and location data, and never hands back a file that is bigger than the one you gave it.

A good compressor removes what your eyes cannot see and keeps what they can. Photos are re-saved with a carefully chosen quality, and the result is checked against the original: if the new file is not smaller, you get your original back instead, with only its hidden data removed. Nothing is ever made worse for no gain.

The before and after slider is the honest test. Drag the divider across a face, a sky or a line of text and look for blur or blocks. Switch to Actual pixels to see every detail at 100%. Most photos look identical at the Recommended level while weighing a third or a quarter of the original.

Phone and camera photos are almost always JPG, and they are often far larger than needed: a 12 megapixel photo can weigh 4 MB or more. To compress JPEG photos, keep Save as on Same format and choose Recommended. Each photo is saved again at 78% quality, which removes invisible detail and typically cuts the size by 60 to 80%.

The photo stays the right way up, because the orientation your phone recorded is applied to the pixels. Camera details such as the date and model can be kept or removed in More options; the GPS location is removed by default, so a photo you share does not reveal where it was taken.

PNG files are lossless, which makes them crisp but heavy. The trick used by well-known tools such as TinyPNG is to reduce the number of colours: a screenshot or illustration rarely needs more than 256, and a PNG with a palette of 256 colours is often 60 to 80% smaller. This page does exactly that, choosing the best 256 colours for each picture, so you can compress PNG files without turning them into JPG.

Transparency is kept, including soft edges and shadows, so logos and stickers still sit cleanly on any background. Smooth gradients in PNG (dithering) blends the reduced colours so skies and shadows do not show bands; for flat logos and screenshots you can turn it off for an even smaller file. If a PNG already has fewer than 256 colours it is stored exactly, with no change at all.

WebP is the modern web format, usually 25 to 35% smaller than JPG at the same visible quality, and every current browser can open it. You can compress WebP files you already have, or choose WebP under Save as to turn JPG and PNG pictures into WebP for your website. Transparency is kept in WebP too.

Safari cannot save WebP from a web page, so on an iPhone, iPad or Mac with Safari the WebP choice is shown as unavailable; use Chrome, Edge or Firefox for WebP output, or keep the same format. AVIF pictures can be added and are saved as JPG or PNG, because browsers cannot write AVIF yet.

Many application forms, exam portals and visa sites accept photos only up to 100 KB. Choose Target size, type 100 and press the button. Each picture gets the highest quality that still fits under the limit, found by trying qualities from the top down rather than by guessing, and the final size is shown so you can upload with confidence.

If even a low quality is too big, the picture is also made a little smaller in pixels, because a smaller sharp photo looks much better than a large blurry one. You can turn that off in the Target size settings. That is the reliable way to compress image to 100KB without ending up with a smeared face or unreadable text.

Job portals, college admissions and government services often ask for documents and photos under 200 KB, and online shops cap product photos at a similar size. Type 200 in Target size, or tap the 200 KB button, and every picture in the batch is fitted under that limit with as much quality as the size allows.

A limit this size is comfortable for a normal photo, so most pictures keep full resolution. Use it to compress image to 200KB for scanned certificates and signatures as well: a document saved as PNG stays crisp because only its colours are reduced. If a file is already under the limit, it is left as it is, at its original quality.

Sometimes you cannot afford any change at all, for example with product photos, medical images or artwork. Choose Lossless. JPG files keep every byte of the picture itself and only lose hidden data: camera details, location, embedded previews and the motion video that some phones attach to photos, which alone can be several megabytes.

PNG files are re-saved more tightly; when a PNG has 256 colours or fewer it gets an exact palette, which can halve its size with not one pixel changed. You can check this yourself with the slider. It is the simplest way to compress image without losing quality, and it even works in browsers that block reading pictures.

Add up to 500 pictures at once, or a whole folder with Add a whole folder. They are compressed several at a time, using the spare cores of your processor, so a batch of a hundred photos usually takes well under a minute on a laptop. A progress bar shows how far it has got, and Stop ends the batch at any moment.

When the batch is done, Download all puts every picture in one ZIP, with the folder structure kept when you added a folder. This makes the page a practical bulk image compressor for an online shop, a blog or a photo archive, with no daily limit and no account.

On an iPhone or Android phone, open this page in Safari or Chrome, tap Select images and pick photos from your gallery. iPhone HEIC photos work without changing any setting and are saved as JPG, which every app and website accepts. To compress photo files for WhatsApp, email or an online form, keep Recommended or set a Target size.

When the pictures are ready, tap Download, or tap Share to send them straight to another app. Phones have less memory than computers, so very large pictures are scaled to a size the phone can handle, and the page tells you when that happens.

Pixels matter more than quality. A photo straight from a phone is often 4000 pixels wide, while a website shows it at 1200 or less. Halving the width and height removes three quarters of the pixels, a far bigger saving than any quality setting, with less visible loss. In More options, Resize scales every picture down to a longest side such as 1920 or 1280 pixels, or any number you type, keeping its shape.

Smaller pictures are never enlarged. To resize without compressing, or to set an exact width and height, use Resize Image; to cut away unwanted edges first, use Crop Image.

Photos carry hidden data called EXIF: the date and time, the phone or camera model, its settings and often the exact GPS location where the photo was taken. By default all of it is removed, which makes files a little smaller and keeps your home address out of photos you share or post.

Choose Keep camera and date to keep everything except the location, useful for photographers and photo libraries, or Keep everything to leave it untouched. Camera data can only be kept in JPG and WebP files.

Your pictures are not uploaded. Reading, compressing, comparing and zipping all happen in your browser, on your own device, using code that runs in this page. That matters for photos of ID cards, passports, documents and anything personal, and it is also why there is no waiting for uploads and downloads.

Because nothing is sent to a server, there is nothing for us to store, log or delete, and the page keeps working if your connection drops after it has loaded. It is a safe way to compress image files you would not want to hand to a stranger.

Each picture is opened by your browser, turned upright and drawn at its final size, with smooth step-by-step scaling for large reductions. Photos are then saved by the browser's own JPG or WebP encoder at the chosen quality. PNG pictures go through a colour reduction step that builds the best palette for that picture, with optional dithering, and are written by a compact PNG encoder that picks the smallest bit depth.

For a target size, each picture is saved at several qualities in a binary search, so the best one that fits is found in about seven tries. The work runs in background workers, one per spare processor core, so the page stays responsive even during a batch of hundreds.

Everything works with a keyboard as well as a mouse or finger. Press Tab to move between controls and Space or Enter to choose. Ctrl+V pastes a picture, Ctrl+Enter starts compressing, and the before and after divider moves with the left and right arrow keys.

Screen readers announce each step: pictures added, progress, and how many are ready to download. Every button has a clear label.

Resize first, then compress. A website rarely needs pictures wider than 1920 pixels, and a message or email rarely more than 1280.

Use JPG or WebP for photos and PNG for screenshots, logos and anything with sharp text or transparency. Choosing the right format often saves more than any setting.

Always compress from the original. Saving an already compressed JPG again and again adds a little loss each time.

Keep your originals. Compression throws away detail for good, so store the full-quality files somewhere safe before replacing them.

Check faces, text and skies with the slider. If something looks soft, go back one level or use Custom with a higher quality.
