Resize, crop and convert your image online – free editor

The tool accepts images in JPG, PNG, and WebP formats. You can add an image in two ways:

• Drag and drop - grab a file from a folder on your computer and drop it onto the file upload area (the area with a dashed border).
• Select from device - clicking the file upload area opens a file selection dialog.

After adding an image, the tool automatically reads its original dimensions and displays a preview. You can now proceed to crop settings.

The tool includes ready-made formats with optimal dimensions for the most popular platforms:

Dimensions in the table are recommended sizes for each platform. The tool automatically sets these dimensions when you select the appropriate format.

After setting target dimensions, an interactive crop area appears on the preview. The bright part of the image is the section that will be saved - the rest is dimmed.

A grid dividing the image into 9 equal parts is visible on the crop area. This is a visualization of the rule of thirds - one of the fundamental principles of photographic composition.

The rule states that the most important elements of a photo (face, product, point of interest) should be placed at the intersections of the grid lines or along them. Such composition is more dynamic and pleasing to the eye than placing the subject exactly in the center.

In the Grid color tab you can change the line color (green, white, black, red, yellow) so the grid is clearly visible on different images.

The dimensions and aspect ratio of a social media graphic influence how much screen space it occupies in a follower's feed - and more screen space means longer exposure time during scrolling. On Instagram, a vertical post (1080×1350 px, 4:5 ratio) takes up roughly 30% more vertical space than a square post (1080×1080 px). This additional real estate increases the probability that a user pauses, reads the caption, and interacts with the content.

Feed aesthetics matter beyond individual posts. The Instagram profile grid arranges thumbnails in rows of three, creating a visual mosaic that visitors evaluate in seconds. Planning the grid in advance - alternating background colors, maintaining consistent crop proportions, and repeating brand elements - builds a cohesive look that signals professionalism. Businesses that maintain grid consistency report higher profile visit-to-follow conversion rates.

Carousel posts (multi-slide posts) on Instagram and LinkedIn allow up to 10 slides per post. Every slide should share the same pixel dimensions and visual style. Inconsistent sizing between slides creates a jarring experience and can cause cropping artifacts on certain devices. Preparing all carousel slides at identical dimensions before uploading eliminates this issue entirely.

A brand color palette should appear consistently across every graphic: backgrounds, text overlays, borders, and accent elements. Cropping images to the exact platform dimensions before publishing ensures that the platform algorithm does not re-crop or letterbox the image in unexpected ways. This level of control over visual output is the foundation of a reliable content strategy.

The rule of thirds divides an image into nine equal sections using two horizontal and two vertical lines. Placing the main subject at one of the four intersections creates a more dynamic and visually engaging composition than centering it. This principle applies equally to photographs, product shots, and social media graphics - the human eye naturally gravitates toward off-center focal points.

Negative space - the empty area surrounding the subject - gives the viewer's eye room to breathe. In product photography, generous negative space around the item draws attention to it without visual clutter. For social media graphics that include text overlays, negative space provides a clean area where the text remains legible without competing with background details.

Leading lines are visual elements (roads, fences, architectural edges, shadows) that guide the viewer's gaze toward the focal point. When cropping an image, preserving leading lines that point inward keeps the composition purposeful. Cutting off a leading line at the edge of the frame can make the image feel incomplete or unbalanced.

The golden ratio (approximately 1:1.618) is an alternative to the rule of thirds that produces a slightly tighter focal area. Some photographers prefer it for portraits and close-up shots. In practice, the difference between rule-of-thirds placement and golden-ratio placement is subtle, but both consistently outperform dead-center compositions in visual appeal.

When cropping for social media, consider which part of the image carries the most visual weight. Move the crop frame so that the focal point - a face, a product, a key detail - sits on or near an intersection point. The crop zoom and position controls in this editor make this adjustment precise, letting you fine-tune placement down to the pixel.

YouTube thumbnails should measure 1280×720 pixels (16:9 ratio) with a maximum file size of 2 MB. The thumbnail is one of the strongest factors influencing click-through rate on YouTube - a clear face crop, readable text, and high-contrast colors consistently outperform generic screenshots. Custom thumbnails receive significantly more clicks than auto-generated frames from the video.

Pinterest favors tall, vertical pins. The optimal pin size is 1000×1500 pixels (2:3 ratio). Vertical pins occupy more space on the Pinterest board and in search results, which increases their visibility and save rate. Product images, infographics, and step-by-step tutorials in this format perform particularly well on the platform.

TikTok cover images should be 1080×1920 pixels (9:16 ratio). This is the same ratio as Instagram Stories and Reels, but TikTok displays the cover as a profile grid thumbnail - important elements should be centered because the sides may be cropped in the grid view. A well-composed cover image makes the profile page look organized and inviting.

Posts on X (formerly Twitter) display best at 16:9 (1600×900 px) or 2:1 ratio. Images that do not match these proportions are cropped automatically in the feed, often cutting off important content. Threads, Meta's text-based platform, supports images up to 1440 pixels wide. Discord server icons require a square image (at least 512×512 px), and Twitch channel banners use 1200×480 pixels.

Each platform applies its own cropping and compression algorithm to uploaded images. Preparing graphics at the exact recommended dimensions - and exporting them in the optimal format and quality - ensures the final result matches the original design. This editor supports all of the above dimensions through custom pixel input or can be matched manually to any platform requirement.

Small businesses and freelancers often manage their own social media without a dedicated designer. A consistent visual identity across posts, stories, and profile elements builds brand recognition - even on a limited budget. The key is establishing a simple brand kit: two or three brand colors, one or two fonts, and a set of standard image dimensions for each platform used regularly.

Batch preparation of weekly content saves significant time. Instead of editing each image individually before posting, prepare all graphics for the week in one session. Set the target dimensions once (e.g., 1080×1350 for Instagram posts), crop and export each image in sequence, and store the finished files in a dated folder. This workflow reduces context-switching and ensures dimensional consistency across all posts.

Freelancers building a portfolio benefit from uniform image presentation. Project screenshots, mockups, and case study visuals should share the same aspect ratio and export quality. A portfolio page with images of varying sizes and aspect ratios looks disorganized and undermines the professional impression the work itself creates.

For businesses that publish on multiple platforms simultaneously, preparing several crop variants of the same source image is efficient. One photograph can yield a 1080×1350 Instagram post, a 1200×630 Facebook/OG graphic, and a 1000×1500 Pinterest pin - each cropped to highlight the most relevant section for that platform. This multi-crop approach maximizes the value of every photograph without requiring separate photoshoots.

This editor processes images entirely in the browser using the Canvas API - a built-in component of every modern web browser. When you add an image, the file is read into the browser's memory (RAM) and rendered onto an invisible canvas element. All cropping, resizing, and format conversion operations happen on this local canvas. The finished image is generated as a downloadable file directly from the canvas data. At no point does the image leave the device or travel over the internet.

Photographs taken with smartphones and digital cameras often contain EXIF metadata - embedded information about the date, time, camera model, exposure settings, and sometimes GPS coordinates of the location where the photo was taken. Publishing images with location data can pose a privacy risk, particularly for personal photos or images taken at client premises. Most social media platforms strip EXIF data during upload, but websites, blogs, and email attachments may preserve the original metadata in the file.

Compared to cloud-based editors such as Canva, Adobe Express, or Pixlr, browser-based processing does not require uploading files to an external server. This means images are not stored on third-party infrastructure, are not subject to external privacy policies, and cannot be accessed by the service provider. For businesses handling client materials, confidential product images, or legally sensitive visuals, local processing eliminates a category of data-handling risk entirely.

The editor also functions offline after the page has loaded. Once the application code is cached by the browser, an active internet connection is not required for cropping, resizing, or exporting. This is useful in environments with limited connectivity or when maximum control over file handling is a priority.
