FAQ
Common questions
Is InstaResizer really free?+
Yes — resizing, compressing, and converting images is always 100% free with no signup required. Background removal is free once per day. Pro ($4.99/mo) unlocks 50 BG removals/month (credits reset monthly, no rollover), batch processing up to 50 images at once, ZIP download, Metadata Stripping (removes hidden location & phone data), white background tool, and an ad-free experience.
What image sizes and platforms do you support?+
We have presets for all major platforms — Instagram (1080×1080 square, 1080×1350 portrait, 1080×1920 Stories/Reels), Facebook & LinkedIn (1200×630 link preview, 1200×1200 square), YouTube thumbnails (1280×720), Pinterest pins (1000×1500), TikTok/Snapchat (1080×1920), and universal profile photos (400×400). Just click any preset and download. Use Fit mode to preserve your full image with a white background, or Fill mode to crop to exact dimensions.
What is Fit vs Fill mode?+
Fit scales your image to fill the full width of the preset while keeping the full image visible — white background fills any remaining space. Fill crops your image from the center to exactly match the preset dimensions. Fit is best when you don't want anything cut off. Fill is best for profile photos and square posts where you want the image to fill the frame completely.
Can I process multiple images at once?+
Pro users can batch up to 50 images for all tools at once and download them all as a ZIP file. Batch mode is available on Resize, Compress, and Convert. Free users process one image at a time using the single image tool.
What is Metadata Stripping and why do I need it?+
Every photo taken on a phone or camera contains hidden metadata — including your exact GPS location, phone model, and the date and time the photo was taken. When you upload product photos to Amazon, Etsy, or other marketplaces, this data goes with them — potentially exposing your home address. Pro users can strip this hidden data with one click before downloading, protecting their privacy automatically.
What's the difference between JPG, PNG, and WebP?+
JPG is best for photos — smaller file sizes with great quality. PNG is lossless and best for logos, graphics, and images with transparent backgrounds, but produces larger files for photos. WebP is the modern web format — typically 25–35% smaller than JPG at the same quality, and supported by all major browsers and social platforms. When in doubt, use WebP for web use and JPG for everything else.
Does my photo get uploaded to your servers?+
Almost never. Resizing, compressing, converting, and Metadata Stripping all happen entirely in your browser — your photos never leave your device. The only exception is AI background removal, which sends your image to our processing partner (Photoroom) and deletes it immediately after. We never store your images.
What image formats are supported?+
We support JPG, PNG, WEBP, and HEIC (the format iPhone cameras use) as inputs. You can convert between JPG, PNG, and WEBP using the Convert tab. All outputs are available as JPG or PNG depending on the tool.
Why does Instagram make my photos look blurry?+
Instagram recompresses any image over 1MB when you upload. By pre-resizing and compressing with InstaResizer first at 85%, you control the quality — and your photos look noticeably sharper in the feed.
What e-commerce platforms do you support?+
Pro users get presets for Amazon (2000×2000), Shopify (2048×2048), Etsy (2000×2000), eBay (1600×1600), Facebook Shop (1024×1024), Pinterest (1000×1500), and WooCommerce (800×800) — all pre-sized to each platform's exact requirements. Batch process up to 50 product images at once and download as a ZIP.
Social Media Image Requirements Guide
Exact dimensions for every platform — updated April 2026. Know what to upload before you upload it.
Instagram
Most used platformCrop to: square before uploading
Crop to: 4:5 before uploading
Crop to: 9:16 before uploading
Displayed at 110×110 — upload at 320px for sharpness
💡 Stories & Reels tip: These are 9:16 — the opposite of a typical landscape photo (16:9). A standard widescreen photo will have heavy white bars top and bottom. In your phone's Photos app, crop to 9:16 first, then upload. Alternatively, use Fill mode in InstaResizer to auto-crop to the frame.
Instagram compression: Instagram recompresses uploads over 1MB. Pre-resize and compress to 85% quality with InstaResizer first — your photos will look noticeably sharper in the feed.
Facebook
Most formatsCrop to: wide landscape
Crop to: square
Crop to: 9:16 before uploading
Crop to: wide panoramic
Displayed as circle — center your subject
💡 Story tip: Facebook Stories are 9:16 — the same as Instagram Stories. A landscape photo (like a 3840×2160 camera shot) is 16:9, which is the exact opposite ratio. This will produce very heavy white padding top and bottom. Crop to 9:16 in your phone's Photos app first, or use Fill mode to auto-crop.
Cover photo tip: The cover photo ratio is very wide (~2.63:1). Panoramic landscape shots work best. Standard photos will have significant padding on the sides — crop to a very wide crop in your Photos app before uploading.
TikTok
Vertical firstCrop to: 9:16 before uploading

YouTube
Thumbnails matter mostCrop to: 16:9 wide landscape
Safe zone: center 1546×423px
Displayed as circle
Channel banner tip: The banner displays differently on TV, desktop, tablet, and mobile. Keep your important content (logo, text) in the center safe zone of 1546×423px. The outer areas may be cropped on smaller screens.
Twitter / X
Wide landscapeCrop to: 16:9 wide landscape

Pinterest
Tall pins perform bestCrop to: 2:3 portrait
Crop to: square
Crop to: tall vertical crop
LinkedIn
Professional contentCrop to: wide landscape
Crop to: square
Displayed as circle
Crop to: panoramic wide
💡 Banner tip: LinkedIn's banner is extremely wide (4:1). Very few photos are naturally this shape — you'll almost always need to crop to a wide panoramic strip or create a custom banner graphic.
