Frequently Asked Questions
Will Gmail accept a 1MB photo?
Yes. Gmail allows attachments up to 25MB, so 1MB photos go through easily — and your recipients will not have to wait long to download them.
Is 1MB enough for printing?
Yes — 1MB JPEGs print beautifully up to A4 (8.3 × 11.7 inches) at 300 DPI. For larger prints, use the original RAW or full-resolution file.
Can I attach a 1MB photo to an iMessage or WhatsApp?
Yes. Both messengers handle 1MB files instantly, and the recipient sees full quality without aggressive re-compression.
Does compression affect EXIF data like camera settings?
Yes — EXIF metadata is removed during compression to protect your privacy. If you need to keep camera settings, use the original file.
