image too large for WhatsApp
WhatsApp's 100MB media cap blocks bigger files. Use Bulk Image Converter to bring your image under the limit while keeping it readable.
It's one of the most-searched questions on the topic: a image just over the WhatsApp attachment limit, and you have to send it now.
WhatsApp's hard cap is 100MB per outgoing message. Anything bigger gets rejected — sometimes silently, more often after you've waited 30 seconds for the upload bar to crawl. The fix is to bring the image below that threshold before you hit Attach.

Why this happens
Images grow for predictable reasons — embedded images at full camera resolution, fonts shipped twice, scanned pages saved at 600 DPI, video clips that were never meant for email. The original was fine for archiving, but it isn't shaped for email. What follows works in every modern browser.
How to bring a image under 100MB
- Open Bulk Image Converter in any modern browser. Nothing installs.
- Drag the image onto the drop zone. Multiple files work too; Bulk Image Converter processes them in a single pass.
- Pick a compression preset. "Balanced" is the right answer 95% of the time — visually identical output, file size cut by 50–80%.
- Wait for processing — usually under five seconds for a image smaller than 50MB.
- Download the result. It lands in your default downloads folder under the original filename, suffixed.
- Attach the smaller version to WhatsApp and send. The size badge in the attachment row should now read well below 100MB.
If you have a stack of images to send to the same person, drop them in together — Bulk Image Converter handles a batch in one click, then you attach the whole folder.
What if it's still too big?
A few images resist compression — usually because they're already aggressively compressed, or they're video / audio at high bitrate. Two reliable next moves:
- Trim or split. If the image is content-rich, sending half today and half tomorrow often beats forcing it into one attachment.
- Switch to a cloud link. Google Drive, OneDrive, Dropbox, and WeTransfer all give you a copy-paste link that bypasses every mail provider's cap.

Frequently asked questions
Does Bulk Image Converter upload my image to a server?
No. Bulk Image Converter runs entirely in your browser using WebAssembly. The image never leaves your device — there is no server to send it to.
Why does WhatsApp reject files over 100MB?
It's a server-side rule, not a client setting. WhatsApp lifted the document cap to 100MB in 2022. Media (photos / video) still has lower per-asset limits.
Is there a way to do this from my phone?
Yes — open Bulk Image Converter in mobile Safari or Chrome and drop the image from your photo library or Files app. The flow is identical to desktop, just with bigger taps.
What's the maximum I should attach to WhatsApp, in practice?
Stay 10–15% under the hard cap. WhatsApp's 100MB is the wire limit, but base64 encoding inflates the body by ~33%. Headroom prevents the "rejected after 30 seconds" failure mode.
