## What is StayUnder?

Tired of frustrating "File size exceeds limit" errors when uploading photos?

Set a maximum file size in KB or MB, such as 300 KB, 1 MB or 2 MB. Choose one photo or a set, compare the measured results, then save or share separate copies. Your original photos remain untouched.

PERFECT FOR:
• Uploading prepared photos to online forms and job applications.
• Email attachments with strict size limits (like 5 MB or 10 MB).
• Real estate listings, school portals, and web forms that reject large images.

KEY FEATURES:
• Choose a Size Limit: Specify a maximum file size in KB or MB.
• Batch Processing: Apply the same maximum to each photo individually, in a single-photo job or a set.
• Live Size Verification: See the measured file size of each prepared image before saving.
• Compare Before Export: Inspect the original and smaller copy at the same scale.
• Non-Destructive: Original photos in your library are never overwritten.
• Full Transparency Support: Keeps alpha channels on static PNG files.
• Local Photo Processing: Photos are processed on your device and are not uploaded to servers.

TRANSPARENT, NO-SUBSCRIPTION PRICING:
• Free: Export up to 3 photos per day for free on this device. The daily count is shared across single-photo and batch exports.
• Lifetime Pro: Remove the daily photo export limit with one purchase. No subscription or automatic renewal.
• Same Great Quality: Free and Pro use the exact same compression algorithms and comparison tools.

TECHNICAL NOTES:
• Supports JPEG, HEIC and static PNG. Video, PDF and animated images are not supported.
• A maximum is not an exact output size. Tight limits can reduce resolution or detail; some inputs produce an SDR copy. Changes are shown before export.
• If a photo cannot meet the limit, review the available result or choose another limit.
• Free counts successful photo exports by the local date. Failed or cancelled exports and repeat exports of the exact same result do not use another free slot. Your regional price is shown in the App Store.

PRIVACY:
Photo contents, filenames and file sizes are not sent to usage analytics. Optional usage analytics can be enabled or disabled in Help. Purchase and restore services operate separately and may use a network connection.
