Same picture, a third of the size
Phone cameras save for the archive, not for the web: a 4-6 MB JPEG carries far more data than it will ever need at the size it is displayed. Save the same photo as WebP and the file typically drops by 60-80% with a difference no one can see.
That pays off directly. Pages load faster, email attachments stay under the limit, and phone storage fills up more slowly. Page speed is also one of Google’s ranking signals, which makes compressing images an SEO task as much as a housekeeping one.
See the quality before you download
Most compressors only show you the result after you download it, and if you do not like it you start over. This one has a before/after slider: drag it across the image to compare the original and the compressed version in the same spot, and set the quality by looking at it rather than guessing.
- WebP — the most efficient choice for website and blog images.
- JPEG — the safe choice when the file has to open everywhere.
- PNG — for logos and graphics that need transparency.
Select several files and each is processed on its own, with the results delivered as one ZIP. Everything runs inside your browser; nothing is uploaded.
How to compress an image without losing quality
Step 1: Add your images
Drop in a single photo or dozens at once. PNG, JPG and WebP are supported.
Step 2: Pick a format and quality
Choose the output format and set the quality. For photographs, 75-85% is usually the sweet spot — a large size reduction with no visible loss.
Step 3: Compare the result
Drag the comparison slider to inspect the original against the compressed version on the same image. Not happy? Change the quality and look again immediately.
Step 4: Download
A single file downloads directly; multiple files come as a ZIP. The size saved is shown as a percentage next to each one.
Frequently Asked Questions
Which format should I choose?
For anything published on a website, WebP: noticeably smaller at the same visible quality, and supported by every current browser. If the file is going somewhere unpredictable — an email attachment, an old system — JPEG is safer. Use PNG when you need a transparent background.
What quality setting should I use?
Start at 75-85 for photographs. Go higher for images with text or sharp lines, where compression artefacts show up sooner. The reliable method is to judge it with the comparison slider rather than trusting a number.
Why doesn’t PNG always shrink by the same amount?
PNG is a lossless format, so the quality percentage does not map onto it the way it maps onto JPEG. This tool shrinks a PNG the way a real PNG encoder does: by reducing the number of colours and the bits spent on each pixel, never the resolution. Above 90% not a single colour changes — the saving comes purely from packing the file better; below that the palette is narrowed step by step, and logos, screenshots and graphics routinely come out more than 80% smaller. If your PNG is already well compressed, you get your file back untouched — under no circumstances will you be handed something larger than you uploaded. For photographs PNG is the least efficient choice: unless you need transparency, WebP or JPEG will be far smaller.
Does compressing also remove EXIF metadata?
Because the image is re-encoded, EXIF usually does not survive — but that is a side effect, not the purpose. If you specifically want to remove location and device data, use the metadata cleaner, which reports exactly what it found and removed.
Is there a limit on batch size?
No fixed limit; your device’s memory sets it. With hundreds of very high-resolution files, working in batches keeps things responsive.
A form wants the photo under 100 KB — is this the right tool?
You can get there with the quality slider, but there is a shorter way: the resize to KB tool applies the KB limit, the pixel or mm size and the DPI in one step, and finds the highest quality that fits by itself.
Are my images uploaded?
No. Compression runs entirely on your device, inside your browser. Your files never touch the network.
