What's the recommended image file size for email marketing?

Most email marketing best practices recommend keeping total email image weight under 1 MB, with individual images under 200 KB where possible. Heavy images increase load time in email clients and raise spam filter scores on some platforms.

Can I compress images for Google or Meta ad creatives?

Yes. Google Display Network and Meta Ads have file size caps (150 KB and 30 MB respectively, varying by format). Compressing at quality 75–80 in Deliteful typically brings standard banner creatives well within limits without visible quality loss.

Will compressing PNG banner images affect text or logo sharpness?

No. PNG files are optimized losslessly — transparency, sharp text, and logo edges are fully preserved with no quality compromise.

Does the tool change image dimensions?

No. Dimensions are preserved exactly, which is critical for ad creatives with exact pixel dimension requirements.

Campaign-Ready Images: Compress Without Losing Impact

Marketing teams sending email campaigns and managing paid ads hit file size limits constantly — email platforms cap embedded image sizes, ad networks restrict creative file weights, and landing pages with heavy images underperform. Deliteful compresses your campaign images to platform-ready sizes in one batch, without a round-trip through a designer.

Email marketing platforms like Mailchimp and Klaviyo recommend keeping total email image weight under 1 MB; Google Display Network caps individual creatives at 150 KB for many placements. Marketing managers who wait for design to re-export every asset before a campaign send create unnecessary bottlenecks. Deliteful's batch optimizer compresses JPEG, PNG, and WebP files in a single session — the marketing team can handle it directly.

The quality slider (1–95, default 80) gives non-technical users a practical lever: 80 for email graphics and landing page images, 70–75 for ad network thumbnails where bandwidth is the priority. PNG files with logos or overlay text are optimized losslessly, so transparency and sharp edges are preserved in banner creatives. All metadata is stripped, cleaning out any internal file references before assets go live.
