Compress an image to under 1 MB

The 1 MB target size is already set. Drop your image, tap “Convert”, done.

or tap to choose. Several files at once.

Choose files

Step by step

  1. Quick check: the “Target size in KB (optional)” field already says 1000 and JPG is selected as the output format. You don't need to change anything.
  2. Drop your photos or scans. The easiest way is to drag in every attachment a form asks for at once.
  3. Tap “Convert”. Each file then shows its new size and the pixel dimensions it was saved with.
  4. For documents, open the result and check that small print, stamps and signatures are still easy to read.
  5. Download the files one by one or as a ZIP, then upload them to the form.

What you can use it for

  • Insurance claims: Photos of the damage need to show what happened. At just under 1 MB per image, scratches, cracks or water stains stay clearly visible and the form accepts the file.
  • Proof for government applications: Scanned certificates, invoices or receipts for an online application can be brought under the limit in one go, without editing each file separately.
  • Contact forms from landlords and tradespeople: If you want to send a photo of a broken appliance or water damage, you often hit a per-attachment limit. A compressed phone photo still shows the problem clearly.
  • Several photos in one message: Once every photo is under 1 MB, you can comfortably send several images in a single email.

Why 1 MB?

Many online forms limit attachments to 1 MB per file: job applications, insurance claims, government applications and contact forms. A phone photo, on the other hand, is often 3 to 6 MB.

How the tool works

First the JPG quality is lowered step by step, which is barely visible. If that's not enough, the pixel dimensions are reduced. This keeps the photo as large and sharp as possible while still landing under 1 MB.

For documents with small text, it's worth checking the result. If the text is still easy to read, you're good.

Frequently asked questions

Will the photo get blurry?

Usually barely visible. A 1 MB JPG phone photo is sharp enough for screens and normal prints.

Can I compress several photos at once?

Yes. Drop them all; they are compressed one after another and can be downloaded as a ZIP.

Does the tool count 1 KB as 1000 or 1024 bytes?

As 1000 bytes. So 1000 KB means at most 1,000,000 bytes. That keeps the file under the limit even if a portal counts strictly in bytes.

Is 1 MB per file or for everything together?

That depends on the form. If it states a total limit, divide it by the number of files and enter the result as the target size, for example 300 for three photos totalling 1 MB.

Should I use PNG instead of JPG?

Not for photos. PNG has no quality levels, so the tool can only reduce the pixel dimensions. At 1 MB, a PNG photo therefore ends up much smaller and coarser than a JPG.

How many pixels will the photo keep?

That depends on the subject. Calm areas like sky or walls compress more easily than fine patterns like leaves or fabric. The actual dimensions appear next to each file after converting.

My image is already under 1 MB – what happens?

It is still saved again, at the highest quality that fits under the limit. If the original is already below 1 MB and accepted, you can simply upload the original.
