Compress and convert images
Change the format, resize, or bring an image down to a specific file size, for example “under 2 MB” for an upload form.

Paste this code where the tool should appear on your website. It contains your personal key.
Free, no sign-up. The tool runs in your visitors' browsers and their files are never uploaded. A small credit to enhancevision.de appears below the tool.
Step by step
- Drag images into the box or tap it to choose them. JPG, PNG, WebP and iPhone photos in HEIC format are accepted, many at once if you like.
- Pick JPG, PNG, WebP or AVIF under “Output format”. If WebP or AVIF carries a note that your browser doesn't support it, that option is locked.
- Under “Dimensions”, decide whether the pixel size stays or changes: cap the long side, set an exact width or enter a percentage. The height always follows the aspect ratio.
- Either set the “Quality” slider or enter a “Target size in KB”. With a target size the tool finds the right quality on its own and the slider no longer matters.
- Tap “Convert”. The list then shows the old and new file size plus the new pixel dimensions. Download files one by one or all together with “Download all as ZIP”.
- If you change a setting afterwards, the finished results are discarded. Just tap “Convert” again.
What you can use it for
- Photos for marketplaces and shops: Product photos from a phone are usually bigger than needed. With “Long side at most …” you bring every image in a series to the same size before uploading.
- Images for your own website: For blog and shop images, WebP or AVIF cuts loading time. A fixed width makes sure every image arrives at the same width in your layout.
- Holiday photos by email: Several photos can be shrunk together and attached as a ZIP instead of running into the mailbox size limit with the full originals.
- Screenshots for tutorials: Screenshots saved as PNG are often needlessly large. “Percent of original” combined with JPG or WebP makes them easier to handle. Check afterwards that small text is still readable.
- Uploads with their own limit: Whether it's 300 KB for a profile picture or 5000 KB for a portal, you can type in any target size and it applies to every file in the list.
Typical cases
- A job portal or government form asks for “max. 2 MB”: enter 2000 KB as the target size.
- Photo for email or online marketplaces: “Long side at most” 1920 pixels and JPG.
- Images for your own website: WebP, long side 1600 to 2000 pixels.
With a target size, the tool lowers the quality first and only then reduces the dimensions until the file is small enough.

Frequently asked questions
How do I compress a photo to under 1 MB?
Drop the image, enter 1000 as the target size and tap “Convert”.
Which format is smallest?
AVIF and WebP are usually smaller than JPG at the same quality. Not every website accepts them, though. JPG works everywhere.
Is transparency kept?
With PNG, WebP and AVIF, yes. JPG has no transparency, so it becomes white.
Are my images uploaded?
No. Everything runs in your browser.
Are small images enlarged too?
Not with “Long side at most …”: if the image is already smaller, it stays as it is. With “Exact width …” and percentages above 100, however, it is scaled up. That makes it bigger but adds no extra detail.
What happens if I combine dimensions and a target size?
The chosen dimensions are applied first. If the file is still too large, the tool lowers the quality and, if necessary, shrinks the image further until the target size is met.
Why does the quality slider disappear for PNG?
PNG is lossless and has no quality levels. With a target size, the tool can therefore only reduce the pixel dimensions for PNG, which becomes visible sooner than with JPG or WebP.
What does “Target size cannot be reached” mean?
The tool reduces the image over several rounds. If the limit is extremely low, for example for a large PNG graphic, that isn't enough. A different output format such as JPG or WebP, or a slightly higher value, will help.
Are camera data and location kept?
No. The image is saved anew, and details such as camera model, capture time or GPS location are not carried over. The photo's orientation is applied correctly first, so it won't suddenly appear upside down.
Can I keep working on the result straight away?
For a single file, a “Continue with …” menu appears next to “Download”. Use it to open the image for cropping right away or to turn it into a PDF.
