Compress Image to 300KB

Drop your photo into this 300 KB compressor, confirm the target size, then cast the spell. Imgician shrinks the file in your browser — no signup and nothing is uploaded to our servers. Need a different limit? Try the custom compressor.

300 KB is the file size on disk, not the pixel dimensions. A 300 KB JPG can be a sharp phone crop or a smaller full-frame shot depending on quality and resolution. See how big a 1MB photo is for more context, or use this tool when a form caps uploads at about 300 KB.

Lossy JPG compression always trades some detail for a smaller file. Starting from a well-lit original and resizing dimensions first (when a portal also asks for width/height) usually looks better than crushing a huge camera file straight to 300 KB.

Yes. Compression runs on your device in the browser. Your image is not uploaded to Imgician’s servers for editing.

Easiest: use Convert JPG to PDF under 300KB (one step). Or compress here, then open the image to PDF converter. Guide: JPG to PDF under 300KB.

Imgician is a free online image toolkit for compressing photos to a target size, resizing dimensions, converting formats like JPG, PNG, WebP, AVIF, BMP, and image to PDF, plus cropping, rotating, flipping, watermarking, removing backgrounds, and passport print sheets — all without creating an account.

No. Compress, resize, convert, edit (crop / rotate / flip), watermark, background removal, and print-sheet layout all run in your browser on your device. Your images are not uploaded to Imgician’s servers for editing, and we don’t store the files you process.

Yes. Open the Sheet tab or the passport photo sheet tool, drop one photo, pick size (3.5×4.5 cm, US 2×2 in, stamp, or PAN), page (A4 / 4×6 / Letter), and DPI, then cast the spell. Download a PDF with multiple copies at true print DPI — nothing uploaded.

Default is 300 DPI (print-shop standard). You can switch to 600 DPI for sharper sheets. Photo cells use exact millimeter or inch sizes so printed copies match the labeled dimensions.

Yes. Open the Cutout tab or Remove background, drop one photo, choose Transparent, White, or a custom fill, then cast the spell. A small AI model (~5 MB) loads once on that page only and runs privately in your browser.

Yes. Cutouts run on your device with on-device AI — Fast (~5 MB), Better (~42 MB), or Premium (~42 MB). Your photo is not uploaded to Imgician for removal. Optional models download once and are cached locally.

The AI weights must reach your browser once so inference can stay local. Fast is about 5 MB. Better and Premium (~42 MB each) only download if you choose them. Other Imgician tools never load these models.

Yes. Open the Mark tab or Add watermark, drop your photo, choose Text or Logo, set opacity and position (or Tile for a repeating stamp), then cast the spell to download. A live preview shows the stamp before you export.

Yes. In Mark mode or on Add logo watermark, switch to Logo, choose a PNG or JPG mark, set logo size and opacity, place it in a corner or center, then cast the spell. Prefer a transparent PNG for clean brand overlays.

In Mark mode or on Copyright watermark, enter your text (for example © Your Name), choose Tile as the position, and optionally enable Diagonal stamp. Tile auto-fits stamp size so the pattern fills the image — tweak Size if you want larger or smaller repeats, then cast the spell.

Open Mark or Diagonal text stamp, type your stamp text, check Diagonal stamp, and pick Center, a corner, or Tile. The preview rotates the stamp about −28° so it reads like a classic proof mark.

Yes. Use the Opacity slider so the mark protects the photo without hiding the subject. For text stamps, pick a Color that contrasts with the background — white or light gray works well on dark photos.

Yes. In Mark mode or Batch image watermark, drop several photos (or use + Add more), set one text or logo stamp for the batch, cast the spell, and download a ZIP. Up to 40 images per batch. HEIC stays one file at a time.

Open Batch Image Watermark, drop multiple photos, choose Text or Logo and shared position/opacity, then cast the spell. When processing finishes, use Download ZIP for all stamped files.

Yes. Text and logo watermarks are applied in your browser. Your photo and logo file are not uploaded to Imgician’s servers for stamping.

Yes. Open the Edit tab or Crop image, upload your image, then rotate 90°, flip horizontal/vertical, and drag the crop box (with optional aspect presets). Cast the spell to download the edited file.

Open Crop image, drop your image, then drag the crop box on the preview. Use the corner handles to resize and drag inside the box to reposition. When the frame looks right, cast the spell and download the cropped image.

Edit mode includes Free crop plus locked ratios: 1:1, 4:5, 3:4, 4:3, 3:2, 2:3, 5:4, 16:9, 9:16, and 21:9 — useful for Instagram, Stories, YouTube thumbnails, profile pictures, and widescreen banners.

Open Crop image to square, drag the box over the face or subject, then cast the spell. Use the result for WhatsApp DP, Instagram, or other avatars.

In Edit or Rotate image, tap Left to rotate counter-clockwise or Right to rotate clockwise. Each tap turns the image 90°. Rotate applies instantly to the preview — then crop if needed and cast the spell to download.

In Edit or Flip image, tap Horizontal to mirror left-right, or Vertical to flip top-to-bottom. Flips apply instantly. Cast the spell after you’re happy with the crop (or use the full frame) to download.

Yes. Rotate or flip first (they update the working image immediately), then adjust the crop box, then cast the spell once to download the final edited file.

Cropping can still re-encode the image (especially to JPG), so file size may go up or down depending on content and format. Editing changes pixels and framing — it isn’t a compressor. Use the image compressor afterward if you need a smaller KB target.

Yes — try batch compress, batch resize, batch convert, or batch watermark. The same settings apply to every file. Cast the spell and download a ZIP. Edit, Cutout, and Sheet stay single-image only.

Open Batch image compressor, drop multiple photos, set your quality or target KB once, then cast the spell. When processing finishes, download the ZIP. Up to 40 images per batch.

Open Batch image resizer, add several images, set the shared width, height, or percent scale, then cast the spell. Every image uses those dimensions. Download the resized files as a ZIP when you’re done.

Open Batch image converter, drop your images, pick one output format (JPG, PNG, WebP, AVIF, BMP, or PDF), cast the spell, then download the ZIP. The chosen format applies to the whole batch.

After casting the spell on multiple images, use Download ZIP. All processed files are packed into one archive so you don’t get dozens of separate downloads.

Yes — up to 40 images per batch. Very large files may also run slower on older phones, so keep sources reasonable when processing a full queue.

Yes. Drop a single HEIC file into Convert, or open HEIC to JPG / HEIC to PNG. Imgician decodes it in your browser, then exports JPG or PNG. HEIC is not available in batch — one photo at a time.

HEIC decoding is heavier than JPG/PNG. To keep the tool fast and reliable on phones, Imgician handles HEIC one file at a time. Convert each HEIC separately with HEIC to JPG, or export JPG from your iPhone first if you need a large batch.

Open the image compressor, drop your image, enter a target size in KB (for example 50KB or 100KB), then cast the spell. Imgician reduces quality and, if needed, dimensions to approach that size while keeping the smaller result.

Lossy compression (typical for JPG) can reduce fine detail to hit a smaller file size. Use a higher quality setting for milder shrinks, leave the target blank for quality-based compress, or try the lossless compressor when you want to preserve more detail — especially for PNGs.

Some images are already well optimized. If re-encoding would make the file larger, Imgician keeps the original and may show “Already optimized.” Try a lower quality, a smaller target KB, or a different format in the converter.

Open Resize image, upload your image, then set width and height in pixels, centimeters, millimeters, inches, or percent. Lock the aspect ratio to keep proportions, then download the resized file.

Yes. In Resize, set the unit to % and enter a scale value (for example 50 for half size). You’ll see the resulting pixel dimensions before you cast the spell.

Imgician supports common conversions among JPG, PNG, WebP, AVIF, and BMP, plus converting an image to a single-page PDF. AVIF export needs a browser that can encode AVIF (Chrome and Safari typically). Pick Convert, choose the output format, and download the result.

Open the image to PDF converter, drop your JPG, PNG, or other supported image, optionally set a target KB, then cast the spell. For ~300KB photo PDFs use JPG to PDF under 300KB.

Yes. Compress, resize, convert, edit (crop / rotate / flip), watermark, background removal, and passport print-sheet tools are free, with no signup required and no per-image fee.

There’s no hard upload quota because files stay on your device, but very large photos can be slower on older phones or low-memory browsers. For the snappiest experience, keep sources under about 10–15MB when possible — or compress to 10MB first.

Yes. You can compress, resize, convert, crop, rotate, flip, watermark, remove backgrounds, and build print sheets on phones and tablets using the same browser-based tools — helpful for form uploads, WhatsApp sharing, and document portals. Background removal may be slower on older phones.
