Features

Everything MetaClean does to make your images ready for any ad platform.

Feature 01

Metadata removal

Ad platforms like Meta and Google scan image metadata before approving creatives. Hidden data points can trigger automated rejections. MetaClean strips all of them before your image ever reaches a platform.

EXIF data

Camera model, lens info, shooting settings, software used — all removed.

GPS coordinates

Location data embedded by phones and cameras is wiped completely.

Timestamps

Creation and modification dates that can flag recycled creatives are removed.

Device information

OS, app version, and device identifiers embedded in the file are stripped.

ICC colour profiles

Embedded colour profiles that can cause rendering inconsistencies are normalised.

Thumbnail previews

Embedded thumbnail images that sometimes differ from the actual content are removed.

All processing happens server-side and files are never stored. Your images are processed in memory and returned immediately.
Feature 02

Ad format resizing

Every platform has its own required dimensions. MetaClean automatically resizes your images to every supported format — no manual cropping, no distortion, no guesswork.

1:1 Square (1080×1080px)

Standard format for Meta Feed, Google Display, and most social platforms.

4:5 Portrait (1080×1350px)

Best performing format on Meta Feed — more screen real estate, higher engagement.

9:16 Vertical (1080×1920px)

Full screen format for Stories, Reels, TikTok, and YouTube Shorts.

1.91:1 Landscape (1200×628px)

Standard for Meta link ads, Google Display banners, and LinkedIn.

16:9 Widescreen (1920×1080px)

YouTube ads, Google Display campaigns, and video thumbnails.

Resizing uses smart cropping — the most important area of the image is preserved automatically using content-aware detection.
Feature 03

Bulk processing

Stop processing images one by one. Drop your entire creative batch and get everything back clean in one go.

Up to 50MB per file

Works with large, high-resolution images without compression loss.

Multiple files simultaneously

Upload your entire batch — all files are processed in parallel.

Batch download

All processed images download automatically as soon as they are ready.

Format preservation

Input format is preserved — JPG stays JPG, PNG stays PNG, WEBP stays WEBP.

Filename handling

Output files are prefixed with metaclean_ so you can identify them instantly.

Free plan: up to 10 images per day. Pro plan: unlimited.
Feature 03.5

Metadata only mode

Not every file needs resizing. The Metadata only mode strips hidden data from any file type — images, PDFs, or anything else — and returns the clean version instantly, with no changes to dimensions or content.

Any file type

Images (JPG, PNG, WEBP), PDFs, and other file formats are all supported. Non-image files are returned unchanged except for metadata.

PDF metadata removal

Title, Author, Subject, Keywords, Producer, and Creator fields in PDF documents are cleared completely.

No resizing or cropping

Your file comes back at exactly the same dimensions and quality. Only the hidden metadata layer is touched.

Batch support

Drop multiple files of different types at once. All are cleaned and returned as a single zip archive.

Same usage quota

Metadata-only processing counts toward the same daily quota as ad format processing. Free plan: 10 files/day.

Metadata only mode is available via the mode toggle in the dashboard and on the homepage upload tool.
Feature 04

AI Autocrop

When resizing to a different aspect ratio, MetaClean uses Sharp's content-aware attention strategy to detect the most visually important area of the image and keep it centred. No subject gets cut off without your input.

Content-aware detection

The attention model analyses the full image and scores regions by visual saliency — faces, products, and high-contrast areas score highest.

Zero manual input required

Just toggle autocrop on and process. No drag, no coordinates — the algorithm places the crop box automatically.

Manual override available

If you want to fine-tune, switch to manual crop mode and drag the box to exactly where you want it.

Per-format control

Autocrop is set independently per format. You can use it on 9:16 but override manually for 1:1 on the same image.

Approximate preview

The dashboard shows a dashed preview of the autocrop region so you can verify before processing.

AI Autocrop is available on all plans including Free.

AI Outpainting

Instead of cropping your image when resizing to a different ad format, AI expands the background to fill the frame. Your product, face, or focal point stays intact — no content is ever lost.

Zero cropping

Switching from 4:5 to 9:16 no longer cuts off your product. AI fills what is missing.

Background generation

The expanded area is generated to match the style, colour, and texture of the original background.

Works across all formats

Outpainting runs automatically for each selected ad format when the crop would otherwise clip the subject.

Subject detection

AI identifies the key subject and protects it — the generated area never touches the main content.

Natural-looking results

Outputs are indistinguishable from natively composed images for the vast majority of ad creatives.

AI Outpainting will be available exclusively in the AI Studio plan. Join the waitlist for early access and founding pricing.

Automatic Ad Copy

Upload your image and receive ready-to-use ad copy for every platform you target. The AI reads the visual content and generates headlines, descriptions, and CTAs tailored to each platform's tone and character limits.

Image-aware generation

The AI analyses your creative — product type, style, and context — before writing a single word.

Platform-specific tone

Meta copy is punchy and direct. Google copy is keyword-rich. TikTok copy is casual. Each platform gets what it needs.

Character limit compliance

Every output respects the exact character limits for headlines, descriptions, and CTAs on each platform.

Multi-platform in one click

One image upload generates ready-to-paste copy for Meta, Google, TikTok, and Snapchat simultaneously.

Editable outputs

All generated copy is editable inline before you copy it — tweak tone, swap words, adjust CTA.
