What size should email attachments be?

Many providers limit messages to 20–25 MB total. Individual attachments around 5–10 MB are safer. Compressed JPGs at quality 65–75 usually land well under those caps.

Should I send JPG or PNG in email?

JPG is almost always better for photos. PNG is appropriate only when you need lossless screenshots with text or transparency.

Will compressed photos look bad in email?

At quality 70, most recipients cannot tell on laptop or phone screens. Avoid extreme compression below 50 unless bandwidth is critical.

Can I compress several photos before sending one email?

Yes. Batch compress, then attach the smaller files or zip them if your client prefers a single archive.

Does stripping EXIF help email size?

EXIF removal saves a little space and avoids sharing location or device metadata unintentionally.

Compress Images for Email

Compress photos for email attachments so they send reliably. FileShrinkr reduces image file size under Gmail, Outlook, and corporate mailbox limits.

Email attachment limits are real

Gmail, Outlook, Yahoo, and corporate Exchange servers enforce message size limits. A few RAW-like phone photos can exceed twenty-five megabytes combined, triggering bounce messages or silent failures on mobile clients.

Recipients on slow connections appreciate smaller attachments too. A five-megabyte download on rural LTE is still annoying; five files at three hundred kilobytes each feels instant.

FileShrinkr targets the email use case with sensible JPG defaults. You compress before composing, so your mail client never warns you at send time.

Recommended settings for everyday sharing

Quality 70 is a strong default for family photos, vacation shots, and office event pictures. Faces remain natural, skies stay smooth, and files often shrink by half or more.

If you send product photos to buyers or detail shots to contractors, bump to 75–80. If you send quick reference snaps where clarity is nice but not critical, 60–65 saves more bytes.

Resize mentally: if the recipient will only view on a phone, you do not need four-thousand-pixel widths. Pair compression with reasonable dimensions for maximum effect.

Corporate mail and security scanners

Enterprise gateways sometimes block large attachments or specific extensions. Smaller JPGs pass more reliably than huge PNG exports or zip bombs mistaken for risk.

Some filters strip metadata for policy reasons. Proactively removing EXIF with FileShrinkr aligns with security expectations and avoids accidental GPS leaks in field photos.

When in doubt, ask IT for published limits. Design your compression target ten percent below the official cap to account for HTML message overhead.

Inline images versus attachments

Marketing emails embed images inline via CID or hosted URLs. Transactional messages still rely on attachments for invoices, proofs, and signed scans. Know which pattern you are using.

Inline images should be aggressively optimized—often under one hundred kilobytes each—because they load even if the user never downloads an attachment. Attachments can be slightly larger because users choose to fetch them.

FileShrinkr helps both paths: compress heroes for inline use and attachments for explicit downloads in the same session.

PDF as an email-friendly alternative

When you need multiple pages—scanned forms, brochures—merge to PDF instead of attaching six separate JPEGs. One PDF feels professional and is easier to forward.

Enable PDF image compression in FileShrinkr to keep merged documents under portal limits. Recipients open one file instead of juggling album order.

If a recipient cannot open PDFs on an older device, fall back to a small set of JPGs compressed with the same quality preset for consistency.

Etiquette and accessibility

Describe attachments in plain language in the email body so screen-reader users know what to expect. Good filenames—`invoice-march-compressed.jpg`—beat `IMG_4092.jpg`.

Avoid sending uncompressed bursts of twenty photos when five curated shots tell the story. Compression plus thoughtful selection respects inbox space.

If someone replies that images are blurry, re-send a higher quality subset rather than the whole album at max compression. FileShrinkr makes it cheap to run another pass at quality 80.

Troubleshooting failed email sends

When a message bounces or stalls at sending, check total attachment weight first. Mail clients sometimes show per-file size but hide cumulative totals across many images.

Split large sets into two messages with descriptive subjects, or merge related scans into one compressed PDF. Recipients often prefer two labeled emails over one giant zip that antivirus quarantines.

If compression still leaves you over the limit, resize in FileShrinkr's editor tab before compressing again. Removing pixels beats crushing quality into artifact-heavy mush.

Save compressed attachments with clear names before dragging them into compose windows. Mail clients sometimes duplicate files when you re-pick from recent downloads, doubling size accidentally.

Holiday newsletters and school updates spike attachment traffic in predictable seasons. Pre-compress entire albums once, store in a shared drive, and reuse the same optimized files across multiple recipient lists.

Apple Mail and Outlook mobile preview attachments inline. Smaller JPGs render previews faster, which helps recipients decide whether to download full albums on cellular data.

How to use this tool

Select photos to email — Gather the images you plan to attach. If there are many, note the total uncompressed size.
Compress at email-friendly quality — Use JPG at quality 65–75. Enable EXIF stripping for privacy.
Attach and send — Download compressed files and add them to your message. Confirm the total size bar in your mail client stays green.
