What is ConvertnEdit (Convert and Edit)?

ConvertnEdit (also known as Convert and Edit) is a free web app for converting and editing audio, image, and PDF files. Processing occurs directly inside your web browser using WebAssembly and client-side web technology.

How do I convert images, PDFs, and audios on ConvertnEdit?

Select any tool from the ConvertnEdit directory (such as Image Converter, PDF Merger, or Audio Converter), drop your file, configure your desired settings, and download your converted or edited output instantly.

Is ConvertnEdit free and safe to use?

Yes, ConvertnEdit is completely free. Files are processed locally inside your browser, ensuring maximum privacy and data security.

Is this image converter free with no file size limits or paywalls?

Yes, ConvertnEdit Image Converter is completely free to use with no subscription fees, credits, or registration required. You can convert unlimited images locally on your device.

Are my private photos uploaded to a cloud server during conversion?

No. All image encoding and format conversions execute 100% locally inside your web browser via HTML5 Canvas and WebAssembly. Your photos never leave your computer or phone.

What is the best format to convert images to for website speed and SEO?

WebP and AVIF offer superior compression compared to traditional JPG and PNG. Converting to WebP typically reduces image file sizes by 30–50% while preserving visual clarity and alpha transparency.

Will converting a PNG to JPG remove its transparent background?

Yes. The JPG/JPEG format does not support alpha transparency channels and fills transparent areas with a solid white background. To preserve transparency, choose PNG, WebP, or AVIF.

How do I convert a picture into an ICO favicon for my website?

Select the PNG to ICO preset or choose ICO as your target format, drop your PNG or JPG logo, and click Convert. You can then download your converted .ico file ready to place in your website root.

How do I resize an image without losing quality or distorting it?

Keep the "Lock Aspect Ratio" toggle enabled. When you enter a new width or height, the complementary dimension will automatically scale in exact proportion. Use high-quality Bicubic or Lanczos resampling for crisp, sharp downscaling or upscaling.

What are standard social media dimensions for Instagram, YouTube, and TikTok?

Instagram Square is 1080×1080 px (1:1), Portrait is 1080×1350 px (4:5), and Stories/Reels are 1080×1920 px (9:16). YouTube Video Thumbnails are 1280×720 px (16:9), and Channel Banners are 2560×1440 px. TikTok videos are 1080×1920 px. ConvertnEdit provides one-click presets for all major platforms.

Are my images uploaded to any server during resizing?

No. All resizing, pixel resampling, and conversions happen 100% locally inside your web browser via HTML5 Canvas with GPU acceleration. No files are ever sent over the internet or saved on remote servers.

Can I resize and export my image to a modern WebP or transparent PNG format?

Yes. You can resize your original photo and export the newly sized image directly to PNG (lossless with full alpha transparency), WebP (small file size), AVIF, JPG, BMP, or ICO.

Is there a limit on how many images I can resize?

No. ConvertnEdit Image Resizer is 100% free and unlimited with no daily usage caps, watermarks, or account registration required.

What is the best image size for Twitter / X header banners?

The recommended size for Twitter / X profile header banners is 1500×500 pixels (3:1 aspect ratio). Remember to leave space in the bottom-left corner where your profile photo avatar overlaps on mobile and desktop.

What dimensions should I use for Twitter / X timeline posts?

For landscape timeline posts, 1600×900 pixels (16:9 ratio) or 1200×675 pixels are ideal. For square posts, 1080×1080 pixels (1:1) are supported without cropping.

Why does Twitter / X crop my uploaded images in the feed?

Twitter automatically crops images that deviate significantly from standard 16:9 or 1:1 aspect ratios. Resizing your photo to 1600×900 ensures the entire image displays directly in the timeline without requiring users to tap to expand.

Are my photos kept private when using ConvertnEdit?

Yes. All image resizing runs entirely in your web browser using HTML5 Canvas. Your images are never transmitted to external cloud servers.
