Acerca de esta herramienta

Image compression reduces a photo's file size by changing how it is encoded, while keeping the pixel dimensions the same and, as far as possible, the visible quality too. It is worth separating the two things people often confuse: resizing changes how many pixels an image has, while compressing changes how efficiently those pixels are stored. A 4000-pixel-wide photo compressed heavily is still 4000 pixels wide. Modern phone cameras are the usual reason people end up here - they produce files of several megabytes each, which are too large to email, slow to load on a web page, and quick to fill up storage. Because photographs contain enormous amounts of detail the eye cannot track precisely, they can usually be reduced by around 88% before any difference becomes visible. Everything happens in your browser: the images are decoded, re-encoded and downloaded on your own device, with nothing uploaded.

Cómo usar esta herramienta

  1. Add your imageDrag it in or browse to select. PNG, JPG, WebP and AVIF are supported, and the download stays in the same format.
  2. Watch the previewThe tool re-encodes on your device and shows a live before/after slider. Pixel size stays the same; only the file gets smaller.
  3. Check the savingTypical photos land around 88% smaller. Drag the slider at 100% zoom if you want to confirm sharpness.
  4. DownloadSave the compressed file. Your original is left exactly as it was.

Por qué usarla

  • Photos typically shrink by around 88% with no visible blur at normal viewing size.
  • Dimensions are preserved, so the image stays as large as it was - only the file size changes.
  • Runs on your device, so private photos are never uploaded to anyone else's server.
  • Same-format output: JPG stays JPG, PNG stays PNG, WebP stays WebP.
  • No sign-up, no daily quota and no watermark on the output.

Usos comunes

  • Getting photos under an email attachment limit without cropping or resizing them.
  • Speeding up a website, where oversized images are the most common cause of slow pages.
  • Fitting images inside an upload limit on an application, listing or government form.
  • Reducing a phone photo library before backing it up or sharing it.
  • Preparing product photos for a shop listing, where load speed affects both ranking and conversion.

Consejos para mejores resultados

  • Compare at 100% zoom, not fit-to-screen. Compression artefacts are invisible when the image is scaled down on screen.
  • If the image is far larger than it will ever be displayed, resize it first - that saves more than compression alone and costs no quality.
  • Photographs compress well; screenshots, logos and text-heavy graphics do not. Those are better kept as PNG.
  • Keep your originals. Compression is one-way, and you may need the full-quality file later for print or re-editing.
  • If you need to hit an exact number like 100 KB, use the Resize Image to KB tool instead.

Errores a evitar

  • Compressing an already-compressed image repeatedly. Each pass adds new artefacts on top of the old ones, permanently.
  • Expecting the image to look smaller on screen. Compression changes file size, not dimensions - use the Image Resizer for that.
  • Pushing quality to the minimum. Blocking and colour banding appear long before the file gets meaningfully smaller.
  • Compressing images destined for print. Print needs the full-quality original; heavy compression shows up clearly on paper.
  • Compressing logos and screenshots as JPG. Sharp edges and text develop halos - keep those lossless.

Preguntas frecuentes

Add your image above. It is re-encoded in the same format in your browser, then you compare before and after and download. Nothing is uploaded and there is no queue.

Yes. No account, no daily limit, no watermark and no paid tier holding back the useful settings.

It is tuned like ILoveIMG: same pixels, no downscale, and a high quality floor so text and edges stay sharp. Use the before/after slider at 100% zoom if you want to confirm.

Photographs typically drop by around 88%. Images with lots of fine detail or noise compress less; already-compressed files and some screenshots save less. Smooth images with large areas of similar colour compress more.

No. The width and height in pixels stay exactly the same. If you want the image to be physically smaller as well, use the Image Resizer - combining both usually gives the largest saving.

No. Compression uses your browser's own canvas and image encoder, so the files stay on your device throughout. The page keeps working even with the network disconnected.

Use the Resize Image to KB tool instead. It targets a precise file size by adjusting quality automatically, rather than asking you to find the right setting by hand.

Yes, though the saving depends on the content. Photographs saved as PNG shrink dramatically; logos and screenshots that are already efficiently stored as PNG will not gain much.

Yes. Add as many as you like and they are processed one after another in your browser. Large batches use memory, so close other heavy tabs if you are doing hundreds.

Re-encoding generally drops most embedded metadata. If removing location data is your actual goal, use the Image Metadata Remover, which is built for that and tells you what it stripped.
