How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
Mailboxes and upload forms often cap the total size of a message, and a handful of full-size phone photos can break that cap on their own. At 700 KB each, a set of ten photos stays under seven megabytes.
The tool searches for the best quality that fits under 700,000 bytes and trims the pixels only when it needs to. Most phone photos keep a width of about 2400 pixels and look nearly identical to the original at normal size.
If you are sending photos to relatives, a landlord or an insurer, the goal is that every picture opens quickly and shows what you meant. At 700 KB that is easy, and nothing is wasted.
Counting the whole message
Limits apply to the message as a whole, and encoding adds roughly a third on top of attachments. Seven 700 KB pictures come to 4.9 MB before encoding and about 6.5 MB after. Work backwards from the limit and divide by the number of pictures to choose a target.
Photos for insurance and repairs
Claims and repair requests need pictures that show detail, such as a crack in a wall or a serial number on a label. At 700 KB a close-up keeps text on a label readable. Take the photo in daylight, hold the camera steady, and compress afterwards.
Sending to people with slow devices
Not everyone reads email on a new phone. An older device opens a 700 KB picture in a second or two, while a 5 MB original may freeze it. A lighter file is a courtesy to the person receiving it.
Multiple pictures, same settings
Add all the photos together and apply the same target, so the set looks consistent. Review the results as a group before you send, and redo any single picture that looks worse than the others.
Cloud links versus attachments
If a set is too large for email even at this size, share it as a folder link instead. The recipient then downloads the pictures when they choose, and your message stays small.
Keeping the picture useful
A photo sent as evidence or for a record should show what matters without clutter. Crop to the subject before compressing, so the 700 KB goes to the crack, the label or the damage and not to the carpet around it.
Add a second wider photo when the context matters, such as which room or which wall.
Names and order
Name the files so that the recipient understands them without your explanation, for example bathroom-crack-1.jpg. Then send them in a logical order. A well-named set saves questions and repeat sends.
Plain ASCII names are safer for older systems.
Frequently asked questions
How many 700 KB photos can I attach?
Check your mail provider's limit, divide by the encoded size, and keep a margin. Many accept roughly 20 to 25 MB per message.
Can recipients print the pictures?
At 2400 pixels wide they print well up to about 8 by 10 inches.
Are phone photos in HEIC accepted?
Photos in HEIC are turned into pictures by your own browser before they are uploaded. Then they compress to your target like any other.
Will my picture rotate correctly?
Yes. The orientation is applied before compressing.
Do I need to register?
No. You can compress without an account.
Is 700 KB the same as 0.7 MB?
Yes, with 1 MB counted as 1000 KB in this tool.
Can I send the photos in parts?
Yes. If the set is too large for one message, split it into two or three parts and give each a clear subject line, so the recipient knows the order in which to open them.
