Frequently Asked Questions
How do I reduce a photo to under 1MB?
Upload your photo and set the target to 1MB. The tool optimizes quality and may slightly reduce dimensions to hit the target. For most photos, the result is visually identical to the original.
Why is 1MB a common attachment limit?
Many messaging platforms (WhatsApp, Telegram) and email clients handle images under 1MB much faster. Larger images are often re-compressed by the platform, reducing quality.
Can I compress a 10MB photo to under 1MB?
Yes — a 10MB JPEG can typically be compressed to under 1MB in WebP format with excellent visual quality, especially if the original dimensions are reduced to web-appropriate sizes.
What format should I use for photos under 1MB?
WebP for web sharing, JPEG for email attachments and maximum compatibility. WebP gives better quality at the same file size.
Does this work with iPhone HEIC photos?
Yes — upload .heic files directly and they'll be converted and compressed to your target size in JPG or WebP format.
