Open the image and choose the template that matches where it will appear: 1080 × 1920 for Stories and Reels, 1080 × 1350 for a vertical feed image, or 1080 × 1080 for a square post. You can reposition and scale each selected format before saving it.

Instagram may crop a photo when its shape does not match the selected post, Story or Reel format. Prepare it first with the matching Gecko PostPrep template, then move and scale the image yourself so you decide what remains visible before uploading.

Begin with the highest-quality original available and avoid enlarging a small source more than necessary. Gecko PostPrep warns when enlargement is required and smooths the result, but no image tool can recreate detail that is missing from the original.

You can select several ready-made sizes from one original and adjust every version separately. The five included templates cover Stories and Reels, vertical feeds, square posts, landscape web and video images, and Pinterest pins.

The correct size depends on whether the image is a story, reel, feed post, square or landscape placement. Gecko PostPrep provides common 9:16, 4:5, 1:1 and 16:9 templates. Platform requirements can change, so verify unusual or advertising placements before publishing.

Resize the image to the dimensions you actually need, then choose JPG or WebP and adjust the quality control. PNG is lossless but can be much larger. Reducing file size normally involves a tradeoff, so review the finished image before publishing.

Choose the Gecko PostPrep template with the aspect ratio you need, then reposition and scale the image inside the frame. This preserves the image’s proportions and avoids stretched faces, circles or objects while giving you control over the final crop.

Depending on the image and device, metadata may include the capture date and time, GPS coordinates, camera or phone details, orientation, camera settings and editing software. Keep “Remove private metadata” switched on in Gecko PostPrep to prevent the original location, device and capture information from being carried into the newly saved image.

Yes. A photo may contain the original capture date and time in its metadata, together with device and location information. Open the image in Gecko PostPrep and keep “Remove private metadata” enabled when saving to prevent the original location, device and capture information from being carried into the new publishing copy. Also check for visible clocks, calendars, tickets or screenshots that may reveal when the picture was taken.

Keep “Remove private metadata” switched on when saving. Gecko PostPrep creates a new publishing copy without carrying over the original location, device or capture information.

Save a new image with private-metadata removal enabled. The new file does not carry over the original embedded location data. Remember that landmarks, street signs and other visible details can still reveal where a picture was taken.

Possibly. A photo may contain embedded location information, and the visible picture may show landmarks, addresses, reflections or other clues. Remove private metadata and inspect the entire image before sharing it.

Screenshots usually do not inherit the original photo’s camera EXIF or GPS information, but the device or capture application may add other metadata. Open the screenshot in Gecko PostPrep, keep private-metadata removal enabled and use privacy areas to hide names, notifications, maps, coordinates or account details that remain visible in the image.

Platforms may remove or change metadata from publicly displayed copies, but their behaviour can change and may differ between uploads, messages and downloads. The safer approach is to remove unnecessary metadata on your own device before uploading.

Metadata is separate from the visible pixels, so removing it is not what reduces visual quality. Gecko PostPrep creates a new image file, however, so the selected dimensions, file format and JPG or WebP quality setting still affect the finished result.

Gecko PostPrep does not currently include a metadata inspection report. After saving, you can inspect the new file with your operating system’s file-information tools or a trusted metadata viewer before publishing it.

Choose the privacy-area tool, add an area and drag it over the detail you want to hide. Resize or rotate it as needed, then select blur and adjust the blur amount.

Open a PNG, JPEG or WebP screenshot and place separate privacy areas over names, addresses, account details or messages. Each area can use blur, pixelation or a solid colour cover.

Add one privacy area for each detail, then move, resize and rotate every area independently. For stronger concealment, choose pixelation or a solid cover instead of a light blur and inspect the saved image at full size.

Sometimes. A light blur or small pixel blocks may leave text or other details recognizable or partially reconstructable. For passwords, account numbers, addresses and similar private information, use Gecko PostPrep’s solid colour cover, inspect the saved image at full size and share only the newly created copy.

Add captions to individual formats and control their font, size, rotation, colour, bold, italic, panel, drop shadow and outline. Watermarks can use text or a transparent logo with signature, protective or repeated layouts.

Yes. Gecko PostPrep adds a text or logo watermark directly in your browser, without uploading your photo or logo for cloud processing. Choose a signature, protective or repeated style, adjust its appearance and save the finished image back to your device.

JPG usually suits photographs and is widely accepted. PNG is useful for screenshots, graphics, transparency and sharp text, but photographic files can be much larger. WebP can create smaller web images when the destination accepts it.

Gecko PostPrep can open WebP and save the finished image as JPG. HEIC input is not currently supported, so an HEIC photo must first be converted to JPEG, PNG or WebP with a compatible tool on your device.

No. Your images are processed inside your browser and are not uploaded to Gecko PostPrep or sent to cloud processing.

Gecko PostPrep is free to use and requires no account, sign-in or subscription.

Gecko PostPrep was created as a useful, privacy-friendly tool and as a way for Gecko Art Studio to learn whether people want a more advanced image-preparation application. Processing takes place on your device, so the free version does not require expensive image-processing servers or cloud storage.

No. All edits are applied to a working copy. Your original file is never overwritten; finished images are saved as new files.

No. It removes the original location, device and capture metadata from the newly saved image, but it cannot remove private information visible in the picture. Review the whole image and use the function available to hide sensitive areas before saving.

Each format has its own crop and layout. Saving confirms that its position, captions and watermark are ready before you continue to the final download step.
