Compress Image to 1 MB

Photos straight from a modern phone or camera are often 4 to 12 MB. Many forms, chat apps and email systems are happier with something closer to 1 MB. Compressing an image to 1 MB is the gentlest preset Dokurapi offers, and for most photos the change is hard to spot on a normal screen.

What 1 MB means on this page

Dokurapi treats 1 MB as 1000 KB, and 1 KB as 1000 bytes. So the target is 1,000,000 bytes, and the tool aims for no more than 940,000 bytes to keep a 6% safety margin. If a site you upload to measures in 1024-byte units, that margin still keeps you under its limit.

Where the savings come from

Two things shrink the file:

1. Resolution. If the longest side is over 2400 px, the image is scaled down to 2400 px. A 4000 x 3000 phone photo becomes 2400 x 1800, which is still sharper than most laptop screens can show at once.
2. JPEG quality. The image is encoded at the starting quality, 84% by default. Only if the file is still above the safe target does the tool lower quality, 10 points at a time, up to 7 times, never below 18%. If the file is still too big at the 18% floor, the tool then shrinks the pixel dimensions step by step (never below 640 px on the longest side) and shows the final dimensions in the result.

With a 1 MB budget, step one alone is usually enough, so the output quality in the result panel is commonly the starting value itself.

Good reasons to use 1 MB

• Uploading a portfolio piece or work sample to a job or freelance profile.
• Attaching photos to an email without hitting attachment limits.
• Submitting achievement evidence. As one example, the SNBP 2026 registration guide in Indonesia allows achievement evidence up to 2 MB as PDF, PNG or JPG, so a 1 MB image leaves comfortable room.
• Storing a lighter copy of photos you want to share widely.

Keep in mind that the output is JPEG. A PNG screenshot with large flat areas or transparency will be converted; transparent parts turn white. For screenshots of text, check sharpness after conversion.

When you have more than one photo

This tool processes one image at a time so you can review each result. If a form wants several photos as a single document, combine them with photo to PDF after compressing. If you only need a smaller image for a strict slot, the general image compressor lets you pick 100, 200 or 500 KB instead.

Nothing is uploaded, EXIF details such as GPS location are removed by re-encoding, and there is no account or daily limit. The receiving site's current instruction is the final authority on what it accepts.
